Subject: Cannot run any gem as non-root user - freebsd 6.2

On my freeBSD 6.2 laptop I recently installed ruby 1.8.6 and ruby gems
from ports.  Then (as root) used 'gem' to update itself and to install
rails.  All of this proceeded without error - although it took so long
I'd hate to have to repeat it.

<code>
# cd /usr/ports/lang/ruby18
# make install
# cd /usr/ports/devel/ruby-gems
# make install
# gem update --system
# gem install cheat
# gem install rails
</code>

(full list of installed gems near bottom)

Now _as root_ I can run any gem I please simply by issuing

# cheat  # to run the 'cheat' gem


But _as ordinary user_ I cannot run any gem at all.  Here is what I see
when I try to run the above 'cheat' gem (exact same thing happens if I
run 'rake'):

<code>
$ cheat
/usr/local/lib/ruby/site_ruby/1.8/rubygems.rb:350:in `insert': no
implicit conversion from nil to integer (TypeError)
        from /usr/local/lib/ruby/site_ruby/1.8/rubygems.rb:350:in
`activate'
        from /usr/local/lib/ruby/site_ruby/1.8/rubygems.rb:65:in
`active_gem_with_options'
        from /usr/local/lib/ruby/site_ruby/1.8/rubygems.rb:50:in `gem'
        from /usr/local/bin/cheat:18
</code>


The same basic pattern holds true for any gem.  It happens when I run
'rails'.  It happens when in a rails project I try to run something like
'rake db:migrate' even though every single file in my project is owned
by that user.

Any ideas?  I scoured the web and ended up empty-handed.  I'm too new to
ruby for you to trust my speculations, but I wonder if it is a
permissions or some other installation issue relating to the 'gem' app
itself.  Just would not know where to look.


Here are a couple of gem admin commands issued by ordinary user:

<blockquote>

/tmp $ gem check     # no output so I assume okay

/tmp $ gem environment
ERROR:  While executing gem ... (TypeError)
    no implicit conversion from nil to integer

/tmp $ gem list -l
