Compiling problem on Solaris

I compiled PostgreSQL-8.2.0 on Solaris 8, but I cannot execute
binaries because it cannot find linked shared libraries, like
libgcc_s.so.

% cd src/interfaces/libp
% rm libpq.so*
% make
gcc -shared -h libpq.so.5 fe-auth.o fe-connect.o fe-exec.o fe-misc.o fe-print.o fe-lobj.o fe-protocol2.o fe-protocol3.o pqexpbuffer.o pqsignal.o fe-secure.o md5.o ip.o wchar.o encnames.o noblock.o pgstrcasecmp.o thread.o inet_aton.o strlcpy.o getaddrinfo.o -L../../../src/port -lsocket -lnsl -Wl,-R'/usr/local/pgsql/lib' -o libpq.so.5.0
rm -f libpq.so.5
ln -s libpq.so.5.0 libpq.so.5
rm -f libpq.so
ln -s libpq.so.5.0 libpq.so
% ldd libpq.so
libsocket.so.1 => /usr/lib/libsocket.so.1
libnsl.so.1 => /usr/lib/libnsl.so.1
libgcc_s.so.1 => (file not found)
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,Sun-Blade-100/lib/libc_psr.so.1

I think the following patch is needed, so that LD_RUN_PATH is also
passed to -R option.
