Tom, I think all the libraries that libpq.so needs are right there. Please
see the following:
libresolv.so.2 => /usr/lib/libresolv.so.2
libsocket.so.1 => /usr/lib/libsocket.so.1
libnsl.so.1 => /usr/lib/libnsl.so.1
libgcc_s.so.1 => /usr/local/lib/libgcc_s.so.1
libc.so.1 => /usr/lib/libc.so.1
libdl.so.1 => /usr/lib/libdl.so.1
libmp.so.2 => /usr/lib/libmp.so.2
/usr/platform/SUNW,Ultra-5_10/lib/libc_psr.so.1

/usr/platform/SUNW,Ultra-5_10/lib/libc_psr.so.1@

So what else could be wrong?
Thank you very much.
