Fedora also uses the /usr/local/lib64 thing for 64-bit platforms, but
the Gnu Radio installer
  works just fine on Fedora x86_64 platforms [at least F12 through F14,
which I've tested
  over the last year or two].

There must be *something* in the setup of a OpenSuse 64-bit system that
confuses "configure", since
  that's where, ultimately, the makefiles get their information from.

Or, perhaps "Fedora" and "x86_64" are special-cased in configure, and a
similar special case doesn't
  exist for OpenSuse?

Regardless, I suspect the answer lies in either "bootstrap" or
"configure" getting slightly confused on
  an OpenSuse system.
