Try port contents py25-gtk, and see what that says (i.e. which version of Python it used).

If you it says "2.3", you need to install "python_select" port, run python_select python25

[vinc17@…]

This gives files in /opt/local/lib/python2.5/site-packages/gtk-2.0 (no files with 2.3 in their component names).

I'm experiencing the same error on Leopard after installing and running "python_select python25":

configure: error: Could not find Python module gtk

What is the specific Python module gtk?

[rhwood@…]

I am perpetually incapable of reproducing (or even producing) this error.

Can someone with the failure do the following: 1) sudo port clean --all avahi 2) sudo port -f uninstall py25-gtk 3) sudo port clean --all py25-gtk 4) sudo port -dv install avahi > ~/avahi.install.log 2>&1 5) attach the file avahi.install.log from your home directory to this ticket

[vinc17@…]

With this, I no longer have the gtk problem. But see bug #13225.

[amgine@…]

log as per instructions (compressed due to sized constraints)

[amgine@…]

Attaching log file:

amgines-macbook:~ amgine$ sudo port -dv install avahi > ~/avahi.install.log 2>&1
amgines-macbook:~ amgine$ port installed avahi
None of the specified ports are installed.
amgines-macbook:~ amgine$ 

[frstan@…]

avahi install debug output

[frstan@…]

note that I still have the bug - Leopard/Intel

[mls@…]

The problem is the Avahi configure script is failing on the pygtk test because that pygtk module fails to import in Python.

I don't know a solution however.

Confirming problem here. Same error when trying to import gtk in Python. Running Intel/Leopard. This broken port is stopping lots of other ports from installing as well. However this bug is probably not so much an Avahi bug as a py25-gtk one, I'd presume.

[conehead@…]

See bug #13337.

[afb@…]

Fixed, r32470.

afb:

checking for python module gtk... no configure: error: Could not find Python module gtk

The problem still exists, though it may not be sourced in the avahi port.

[afb@…]

avahi should now configure, after installing:

• py25-gobject @2.14.0_1+darwin_9
• py25-gtk @2.12.0_1+darwin_9
• dbus-python25 @0.82.2_1+darwin_9

(those all have the symbol export workaround)

[munsell@…]

I'm still experiencing this problem with leopard and macports v.1.6.

I've installed and ran the python_select port (I'm assuming this is symbol export workround) and tried several times uninstalling and installing these packages - and every time avahi fails with the same error (cannot find python module gtk).

This is probably something simple I'm just overlooking ...

Replying to afb@macports.org:

avahi should now configure, after installing:

• py25-gobject @2.14.0_1+darwin_9
• py25-gtk @2.12.0_1+darwin_9
• dbus-python25 @0.82.2_1+darwin_9

(those all have the symbol export workaround)

[rhwood@…]

I am incapable of reproducing this issue. Can anyone still reproduce it, or is it OBE (overcome by events)?

[amgine@…]

<shrug> I've given up on using macports with Leopard. Can't help.

Closing with comments from Guido Soronzio via email:

This problem has been solved some months ago and it is due to the new Apple's libtool in Leopard.

I applied a simple workaround to many python ports whose makefiles make use of the flag "-export-symbol-regex" by simply removing it and so making the missing symbols public again.

This rough trick works also with apache2 and the missing symbol "_ssl_cmd_SSLCACertificateFile" (#13182) but it has not been committed.

pogma is reporting on his blog that using the new libtool 1.5.26 instread of the Apple's one can alleviate such troubles: ​http://pogma.com/2008/02/13/nmedit-libtool-exported-symbols/.

Sorry to resurrect old, old bug, but I just ran into this installing avahi @0.6.31_13 on snow leopard with libc++. For those who may search here for information with the same issue, the problem in my case was cairo, which was installed without the +x11 variant.

cairo @1.14.6_0+quartz-x11 (active) platform='darwin 10' archs='x86_64'

upgrading cairo to include the x11 variant

cairo @1.14.6_0+quartz+x11 platform='darwin 10' archs='x86_64'

solved the issue, python 2.7 then found the py-gtk module successfully, and the installation of avahi went along smoothly.
