Graham,
thanks a lot for devoting your time and energy to help me (even more
thanks for mod_wsgi overall!:).
Setting correct WSGIPythonExecutable or WSGIPythonHome didn't help.
ldd mod_wsgi.so output is
linux-gate.so.1 => (0x00381000)
libpython2.6.so.1.0 => /usr/lib/libpython2.6.so.1.0 (0x00add000)
libpthread.so.0 => /lib/tls/i686/cmov/libpthread.so.0 (0x00a80000)
libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0x00110000)
libutil.so.1 => /lib/tls/i686/cmov/libutil.so.1 (0x00114000)
libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0x001f0000)
libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0x00386000)
libz.so.1 => /lib/libz.so.1 (0x00118000)
/lib/ld-linux.so.2 (0x00581000)
so i've started playing around with setting the PATH and
LD_LIBRARY_PATH env variables.
But as i need to travel a bit tomorow, I'll finish the testing and
post the results of the PATH and LD_LIBRARY_PATH "method'
in two days, hope that's fine.
thanks again,
greetings,

p.s. this is the bin/python (as said, just a wrapper script), maybe
it's important as well...:
