No: lib dirs in setup.cfg are unused and have been dropped recently.
Only the results from pg_config are used now.

I wouldn't have expected this to be requested. But what was the source
dir exactly? Didn't you have /usr/local/lib/libpq.so?

This sounds strange to me: the only problem is usually to find the
libpq. When psycopg.so is loaded, the python-related libs have already
been loaded.

You can try running the test suite with "make check", after setting
the PSYCOPG_TESTDB_* env variables and maybe creating a scratch db.
See tests/testconfig.py to check what are the vars used and their
default.
