The point is that your from-source build of psql might be linking
to an out-of-date copy of libpq.so provided by the OS.  Linux
machines tend to do that (i.e., prefer libraries in /usr/lib[64])
unless you mess with the dynamic loader's configuration.

Try "ldd /path/to/psql" and see what it says about which libpq
is getting used.
