(Mac)Vim seems to be picking up
Seems like it is an entirely compile-time thing:
$ ldd /usr/bin/vim | grep python libpython2.5.so.1.0 => /usr/lib/libpython2.5.so.1.0 (0xb6bcc000)
vim --version also reports being built against a specific python.
$ vim --version | tr '-' '\n' | grep python +python +quickfix +reltime +rightleft +ruby +scrollbind +signs +smartindent I/usr/include/python2.5 L/usr/lib/python2.5/config lpython2.5
another symptom of this is that the
:python command won't work with vim unless
vim --version reports +python.
