Perhaps you haven't linked against all the required libraries. This was
just being discussed in the thread "Problem with linking embedding C
application".

For something quick and dirty, do a ldd $PYTHONROOT/bin/python and link
against these libraries:

gerhard at lilith:~ > ldd /usr/bin/python
        libpthread.so.0 => /lib/libpthread.so.0 (0x40025000)
        libdl.so.2 => /lib/libdl.so.2 (0x4003b000)
        libutil.so.1 => /lib/libutil.so.1 (0x40040000)
        libm.so.6 => /lib/libm.so.6 (0x40043000)
        libc.so.6 => /lib/libc.so.6 (0x40062000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

So I also link with -lpthread -ldl -lutil -lm.

HTH,

Gerhard
