Subject: Odd Ruby/Rubygems/gem path problem

I've spent too much time trying to solve this little problem. I wonder
if you can help:

I work on a Mac OS X Leopard. I recently started using a different
account as my primary login. Things that shouldnt have, started
breaking. I suspect permissions, file ownership etc problems. But
check this out

# I am using shoulda as a random example gem, this example has nothing
# to do specifically with shoulda

# see that I do have shoulda installed:

$ gem which shoulda
(checking gem thoughtbot-shoulda-2.10.1 for shoulda)
/opt/local/lib/ruby/gems/1.8/gems/thoughtbot-shoulda-2.10.1/lib/shoulda.rb

# see that I have Ruby automatically searching for gems
$ echo $RUBYOPT
rubygems

# see that my ruby install works for a trivial case
$ ruby -e "puts 1"
1

# see that it refuses to see the shoulda gem from the command line
$ ruby -rshoulda -e "puts 1"
ruby: no such file to load -- shoulda (LoadError)
$ ruby -rubygems -rshoulda -e "puts 1"
ruby: no such file to load -- shoulda (LoadError)
$ ruby -rubygems -rshoulda -e "puts 1"

#see this trivial program:
$ cat test1.rb
require 'rubygems'
require 'shoulda'
puts `gem which shoulda`/mydev/graphicsplay

# does work as expected
$ ruby test1.rb
(checking gem thoughtbot-shoulda-2.10.1 for shoulda)
/opt/local/lib/ruby/gems/1.8/gems/thoughtbot-shoulda-2.10.1/lib/shoulda.rb
/mydev/graphicsplay$

### Any ideas would be greatly appreciated. It's probably something
stupid I am just missing it...

Thanks!

Pito
