Python Binary link missing in /opt/local/Library/Frameworks/Python.framework

[aubonbeurre@…]

I found out why mod_python25 gets to link with the system's python, instead of the python25 framework in macports: the Python framework made by macports is not compliant with a framework layout. If I add a link in /opt/local/Library/Frameworks/Python.framework to ./Versions/2.5/Python, then the linker picks up the right Python framework.

I'm using latest xcode 3.1 on 10.5.5, and could reproduce the problem on different machines.

Notice this is not enough to fix mod_python25, which has another unrelated problem during validation (AFAIK).

Sorry for giving so few details, and not being able to test on macports SVN.

Have you installed the python_select port and used it to select 2.5: sudo python_select python25? That will set python25 to be the current default for MacPorts.

Seems like a bug in mod_python25, since its configure script is passed --with-python=${prefix}/bin/python2.5.

I confirm this bug. I have modified the Portfile to build mod_python25 against python26 and not python25 (which I have not installed since it cannot be built universal) and I have this error:

I'm trying to figure out what is going on

PS : I also confirm the fix via a manual ln -s

Probably duplicate of #17205.

As a workaround, try

sudo python_select none
sudo python_select python25

[hvrmeer@…]

If I have understood correctly, that should be:

% sudo ln -s ./Versions/2.5/Python Python

And it did not work for me. My mod_python still chooses /usr/bin/python. Oddly enough, I don't see anything in the error log.

Can someone please tell how I can fix this? I really do want to get on with things.

[raimue (Rainer Müller)]

Please use the latest python_select.

I am still seeing problems here when compiling python extensions:

So in spite of python_select having set python25 as the version, I still see an extension being bound to python25-apple.

I'll file a separate bug, as the symlink (as reported by this bug) is present.

[steenzout (Pedro Salgado)]

I did

sudo python_select python25

and only after I did

sudo port install mod_python25

and it worked for me.

I spoke too fast.
