[Clusterusers] glibc version on fly, cluster

[Wm. Josiah Erikson]

Unfortunately just about everything depends on glibc, so it's likely to

clustering world aren't encouraging. Maybe compiling statically-linked
binaries might be the way to go, not sure. I'm unlikely to have time to
look at this this week, but I'll try.
