Hello Peter,
first make sure that you don't have any "suspicious" rubygem based
executables in your path that might confuse things. Some time ago
I found some ancient such files in /usr/local/bin ...
Next, with a default ruby/rubygems installation, a normal user should
be able to install gems into their own $HOME/.gem directory. I'm doing
this on several gentoo boxes, never had a problem with that approach.
On one of the servers, I can run the following command, to which you can
compare your environment
$ gem environment
