I was able to compile and run the testlibpq.c example on Fedora 12.  I
deleted the entire installation tree after compiling it, so there was
no dynamic libpq to be found.

gcc -I$HOME/project/include -L$HOME/project/lib testlibpq.c -o
testlibpq -static -lpq -lpthread

It might help to troubleshoot if you could provide more details on
exactly what you did, including the compiler invocation.
