All the libraries in that the above faqts reveal are linked with the new
.so (actually one was missing ieee - but didn't change anything).

Hmmm, from what i find all the modules are on the sys.path line:
in CGIX.py PATH: ['/usr/bin', '/var/www/cgi-bin', '/usr/lib/python1.5/',
'/usr/lib/python1.5/lib-dynload/', '', '/usr/lib/python1.5/',
The double paths are because i tried to meddle with the PYTHONPATH
environment variable.... it still *cannot* find the .so files - how
can i tell?
when importing a module (selfmade) - every import works except for
things like "import time" (which uses
IF i load all the .so's in the python path with the new .so (my embedded
python interpretor for RM/Cobol) then everything works - BUT will fail
the moment a distutil install has been done - and someone tries to load
the new module [of course assuming that the distutil module uses a
binary module (.so)]
