32-bit programs needing libssl.so on 64-bit?

I'm not sure on the details of how libraries are placed under RHEL4, but
it should be sufficient to install a 32-bit build of openssl to
somewhere that isn't going to clobber the 64-bit version, and to invoke
the closed-source program with LD_LIBRARY_PATH set to the place that
you've installed the 32-bit libssl.so

e.g. if 32-bit libssl.so is in /lib32
LD_LIBRARY_PATH=/lib32 program_name

or possibly (depending on exact requirements)
LD_PRELOAD=/lib32/libssl.so program_name

Have a look at 'man ld.so' for details and other options.
