I downloaded a tar-ball, and did the install on CentOS 6.3,
a Red Hat Ent. Linux clone, minus branding.

I remember "loadable modules", that can be arranged
with ldconfig and the *so* "loadable modules" or
"plugins" directories and files.

CentOS 6.3 , 64-bit version.

I installed from source.

Up-Key doesn't work.
