Look at this:

It's building a program called gen_test_char and then running it. While
compiling it suggested finding that lib in /usr/local/pgsql/lib. That
worked, so you program compiled and linked fine.

But when you run it, the loader doesn't know where to find that library and
looks in the list in /etc/ld.so.conf. So you have a few options:

1. Add /usr/local/pgsql/lib to your ld.so.conf and run ldconfig
2. Soft/hard or copy the library to /usr/local/lib (if that's listed)
  or even /usr/lib of you prefer.

Don't forget ldconfig.

Hope this helps,
