hmm, there should be something like
-R /usr/local/lib/gcc/lib/gcc-lib/sparc-sun-solaris2.8/3.2

Ok, from your first mail (sorry, didn't read that before ;-)

So your compiler look for libstdc++.so.5 in /usr/local/lib at linking time.
But your executable doesn't know how to find the lib.
The runtime library search path should also point to /usr/local/lib, so
use
LDFLAGS='-L/usr/local/lib -R/usr/local/lib'

Solaris doesn't have an /etc/ld.so.conf like Linux to provide
a lib. search path. You have to use -R or add the flags to your
compiler specs. -R/path under Solaris is the same as
-Wl,-rpath,/path under Linux.
