Gems problem

Ok sorry if this is in the wrong place, didn’t really know where to

I was running ruby 1.8.5 and install rubygems, requiring gems in a
script worked fine and the world was a sweet place… Then i decided to
upgrade to ruby 1.8.6… Then the nightmare came… I tried re-installing
gems 5+ times but no luck… every time i get this error…

blah.rb:3:in `require’: no such file to load – rubygems (LoadError)
from blah.rb:3

or running gem from command line produces this:

/usr/bin/gem:9:in `require’: no such file to load – rubygems
from /usr/bin/gem:9

Each one obviously meaning the same thing… I have no idea what to do.
Does anyone have any idea’s?

Im running deb etch if that helps…

Thanks in advance

Also, i have just checked and /usr/lib/ruby/gems exists with ALL of my
gems in it… I tried to aptitude remove the files but even ruby1.8 wont
un-install… Im so stuck
