ImportError while running cgi-bin on localhost - u

Question

I'm trying to run a cgi-bin site on localhost. And I get the following error:

<type 'exceptions.ImportError'>: /usr/local/lib/python2.7/dist-packages/psycopg2/_psycopg.so: undefined symbol: lo_truncate64

My current PostgreSQL version is 9.4.5.

How can I fix the issue?
