Help Wanted for running C code

Hello help wanted asap for this one please.
I have installed POstgres on my own machine and i am
in charge of its settings.

the problem is when i try and run a small piece of c
code i get an error which states the following:
cc testing_connection.c -L/usr/local/pgsql/lib -lpq
-I/usr/local/pgsql/include -o fred -O0
$ ./fred
./fred: error in loading shared libraries: libpq.so.2:
cannot open shared object file: No such file or
directory

the program followed all the steps set out in the
postgres documentation on building Libpq programs.
But i still get the above??
Any suggestions please
