Switch to Python 2.7 than evolution compiles.

please add your emerge --info and the build.log as suggested by bugzilla/portage.

Did you run an emerge --sync before starting to build anything ? From the look of the ebuild it should automatically select python2 for build and it appears to work here.

[Comment 5 Jens Kasten 2012-11-26 11:50:36 UTC]

I did it now. But the same result.
emerge --sync running always on the local fileserver from where I get the portage tree.

Same thing happens for me. Sync'ed yesterday afternoon the last time.

Fixed in cvs, thanks for reporting. Evolution-3.4 and earlier used a non-standard way of detecting the python interpreter, so to force it to use the correct python, we need to add pythonpath="$(PYTHON -2 -a)" to configure arguments.
