You need to tell gcc where to find  You do that with the -L 
option.  So find (I don't know where it is in the compile tree) 
and then add -L/path/to/libpq to the command.

So you might end up with something like:

gcc -I../../../src/interfaces/libpq -I../../../src/include 
-L../../../src/lib testlibpq.c -o testlibpq -lpq

Again, I don't really know where is, so find it and substitute 
the real path for the one above.
