This could be a name mangling problem. Maybe the linker needs to be
invoked specially when building C++ libraries. Maybe the C++ compiler
driver needs to be invoked directly. This could especially be a problem
if you're using the GNU compiler with system libraries, since those are
usually compiled by the system compiler.

I think the good C++ compiler on AIX is called xlC. In any case, make
sure that you don't mix different C++ compilers. You need to do 'gmake
clean' at least in the libpq++ directory if you're switching.
