Sorry. The above should have read "import _psycopg".

Ok, now we're getting closer.

Could you run this to have Python print the locations where
it looks for the shared lib:

export PYTHONVERBOSE=2
./hello

This should print a long list of messages such as these:

import os # frozen
import errno # builtin
import posix # builtin
import posixpath # frozen
...

to stderr. Of those only the lines which mention _psycopg are relevant.

Please make sure that the dir where the .so file resides is
included in this list. If not, you will need to adjust PYTHONPATH
accordingly.

If the dir is mentioned in the listing, we have to dig deeper
using strace or similar.

Thanks,
