py-gobject and dependents' configure builds using the wrong (/usr/bin/python) version 2.3

[aphor@…]

Python <--> Gnome library packages and their dependents install without error, but fail with import errors at runtime. Whole swaths of software will likely break on upgrade causing widespread panic.

The port for py24 installs itself as /opt/local/bin/python2.4 but configure scripts for py-* packages like py-gobject, py-gtk2, and probably others allow configure to build against the system /usr/bin/python, which is the wrong version of python according to ports' dependency graph. This also causes the python modules to be installed in /opt/local/lib/python2.3/site-packages, which made it easy to track this down.

Workaround: prepend /opt/local/bin to your path, and symlink /opt/local/bin/python2.4 to /opt/local/bin/python because these configure scripts choose their python version by the first executable 'python' on the PATH.

Back when py-gtk2 was in use (it's now deprecated for py25-gtk), the python24 port did provide a /opt/local/bin/python (but it was removed in r28120 to make room for python25). But nowadays it is required to either patch all the old python ports or run python_select.

Or install the python_select port and run python_select python24, which does the same thing...

i.e. /usr/bin/python (Python 2.3 on Tiger, Python 2.5 on Leopard) is now the default python, by design.

[gui-dos (Guido Soranzio)]

r33474 syncs py-gobject, py-cairo and py-gtk2 with their py25-* counterparts, since the formers already made use of the python24 group: now MacPorts' own version of python2.4 is detected during the configure phase.
