Python 2.5 fails at final linking with this error:

!!! ERROR: dev-lang/python-2.5_rc1 failed.

Attached patch fixes this, by changing the linking
order from "Modules/python.o -L. -lpython2.5 -lpthread
-ldl -lutil -L/usr/lib -lz -lm" to "Modules/python.o
-lpython2.5 -L. -lpthread -ldl -lutil -L/usr/lib -lz
-lm" , basically swapping "-L. -lpython2.5" around. The
patch edits configure.in and swaps them for Linux, BSD
and SunOS.

Can you please provide exact instructions on how to
reproduce the problem?

The patch looks wrong. If libpython2.5.so has references to
libz, then it should be linked with libz itself (rather than
linking the executable with libz).

Notice that the procedure to create a shared libpython is
mostly unmaintained and unsupported; so patches to improve
it would be appreciated.

Sorry for noise, I can't reproduce this anymore.
