That won't help. LD_RUN_PATH is not a variable that the Solaris dynamic 
linker uses. Nor would it matter anyway, since his OpenSSL libraries are 
static.

This is a link ordering problem, because he's using static OpenSSL 
libraries and has listed -lcrypto before -lssl. As any Unix programmer 
knows, static libraries must be linked in a specific order, with the 
libraries that reference external symbols listed before the libraries 
that satisfy the references. libssl relies on libcrypto and therefore 
must be listed before it in any link command.

Change LIBS to be "-lssl -lcrypto" and the problem will disappear. 
Better yet, fix your OpenSSL install to build shared libraries.

Note that you shouldn't need to have "-lsasl2" explicitly listed in 
LIBS; configure will look for it automatically.
