I downloaded a tarball, 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 , 64bit version.
I installed from source.

UpKey doesn't work.
