For CentOS systems, the best way is probably using the released RPMs.

What is the output of these two commands:
    ldd `which gmond`
    ls -l /usr/lib/libganglia*

I believe that is being worked on.  A recent change by the sf.net
admins screwed up a bunch of our documentation.

That said, and as I mentioned above, the RPM packages should work just
fine on CentOS.  If they don't, we'd like to hear about it so we can
fix them.

The error means that gmond is trying to load a shared library
(libganglia-3.1.2.so.0), and is failing for some reason.
