I just found an old posting from 2010-08-15. I added the below. If fixed the issue. But I have never had to add this
before. I don't manage the server I run the database on. It might be the case that there was an upgrade of Red Hat
sincethe last time I installed that is causing this to be an issue.
setenv LD_LIBRARY_PATH

This looks like psql is picking up a rather ancient version of libpq.so.
Applying ldd or local equivalent to the psql executable would help you figure out where it's getting that library from.
Bottom line though is probably that you forgot to worry about rpath or something similar while configuring the new
build.
