Is there a work around or hack where I can get the agent installed and tested? - Can't say. But google would be a good place to start with.
Is Centos not supported (I don't specifically see that on the SCL, but do see GNU/Linux under Debian and of course Redhat)?The only supported versions of linux are listed in the SCL. If the version you are running is not listed then it's not supported at this time, but may be supported in an upcoming release. (short answer, it's not supported).
