I think that Simon has shown how you can debug what is going wrong.
I'm just replying to clarify a few things:
1. 2.7 is fine for me (in /usr) :
checking for a Python interpreter with version >= 2.5... python
checking for python... /usr/bin/python
checking for python version... 2.7
checking for python platform... linux2
checking for python script directory...
${prefix}/lib/python2.7/site-packages
checking for python extension module directory...
${exec_prefix}/lib/python2.7/site-packages
2. My comments on dependency versions were aimed more widely - if a
package is not commonly built, it is possible that it doesn't build
with a newer version and nobody will notice for some time. But glib
is *very* commonly built. Because it built fine for me with 2.7, I
didn't include the details in my original reply.
3. The old changelogs show that BLFS has been using Python-2.6.1 or
newer since December 2008. Building 2.5 would not be a good idea.
