Hi Francesco,

There is surely value in having a mixture of setups for the buildslaves?
So certainly some should use RVM, but it seems wise to have others
using a more old fashioned installation? Just my perspective from the

For this particular machine, I wasn't planning multiple installations of
ruby, just Ruby 1.9.x only. I'll leave setting up and looking after a
multi-target BioRuby buildslave to you guys ;)

The Ruby website seemed to suggest going with the source code
installation for me:

"Installing from the source code is a great solution for when you are
 comfortable enough with your platform and perhaps need specific
 settings for your environment. It’s also a good solution in the event
 that there are no other premade packages for your platform."

Well there are Ruby 1.8 packages for CentOS 5.4 but that's too old.

Any ideas on the libyaml problem?
