What happens if you do NOT change the library path in front of it?

[donmez]

Then it won't run as expected (I got python 2.4 installed system wise) :

./python: error while loading shared libraries: libpython2.5.so.1.0:
cannot open shared object file: No such file or directory

[donmez]

Any other thing I can do to debug this?

[tiran]

Yes, can you tell us the content of port2 and service?

[donmez]

This was a glibc regression on my side, it can be closed as invalid. Thanks!

[Tinctorius]

Reproducable with Python3.0rc1 on Debian lenny, only when nscd is running.

Not a Python bug.
