Build from source? Your basic problem here is that your platform's
set of libraries doesn't match what was used by whoever built the
Postgres packages you're trying to install. It's unlikely that
they'll be excited about adding yet another platform variant to
their list of builds (especially not if it's a long-since-obsoleted
variant). But the great thing about open source is you can build
it yourself.

In the Red Hat ecosystem I'd suggest grabbing the corresponding SRPM
and seeing if you can build binary packages from that locally, rather
than resorting directly to raw Postgres source code. I don't know the
equivalent terms in SUSE's packaging system, but I'm sure it works
roughly the same.
