and (even strace) does not show an attempt to acces the so-file. Also tried to add
-L/usr/lib/python3/dist-packages/psycopg2 -l_psycopg.cpython-34m-x86_64-linux-gnu.so
and similar without success.
Can anyone try to reproduce it, a freeze (with patches) of hello.py containing only
import _psycopg2
or maybe another external library? In the first case apt-get install python3-psycopg2 is necessary.
