I set the GEM_HOME variable as you suggested, but no luck.

Here's more detail into the nature of the problem.

I can run both versions of ruby from my [home] as such:

[home]$ /usr/bin/ruby -v
ruby 1.8.4 (2005-12-24) [i586-linux-gnu]

[home]$ ruby -v (or /usr/local/bin/ruby -v)
ruby 1.8.6 (2007-03-13 patchlevel 0) [i686-linux]

No problem ro run gem as root:

[root]# gem -v
0.9.2

But if I try to run gem from my [home], problems:

[home]$ gem -v (or /usr/bin/gem -v)
/usr/bin/gem:9:in `require': no such file to load -- rubygems
(LoadError)
        from /usr/bin/gem:9

I put a symbolic link in my /usr/local/bin;  ln -s /usr/bin/gem gem
but  that wouldn't let me run gem from [home] either.

Is this a rubygems problem?
Do I have to put a separate copy of rubygems in my [home] dir for it
to work there?

I also looked into the rubyconfig.rb file, but it didn't seem that
needed any change.

HELP!
