Sounds like the library is not on the directory you think it is; 
on my system (an out-of-the-box RedHat), the library is located 
on the default lib path (/usr/lib/libpq++.so.*); so, you might 
try a:

find /usr -name "libpq++*" 

To figure out where it is, then adjust the -L switch accordingly.

HTH,
