I have merb setup but when I try to run it I get issue with any gems I try to include, e.g. I have the following:
require 'RMagick'
The rmagick gem is installed, and doing the above in irb (after requiring rubygems works as expected) even putting require 'rubygems' before I require RMagick doesn't fix the issue.
Ah-ha seems that it was getting confused with the frozen(?) gems in the gems/ directory under my app, removing that completely fixed the issue. Will look into that further.
