Isn't the problem that you don't have 'psycopg' python module on your
system? I've tried it now on my box an run into similar problems.

that's known problem, gdal-config tool in ubuntu feisty package

Eh, I have never seen or heard of pyqtconfig_nd - what's that? where is it from?

Why? it must compile also without it being set.

I think that's because of some permissions problems. Probably you've
