sudo driving me crazy!! (ruby, gem)

OK, I just installed Ruby EE on my new linode.

I am using Ubuntu 9.10 and it didn't have Ruby previously.

I have the following setup as my PATH in ~/.profile (both for my login account AND root)

/opt/ruby-enterprise-1.8.7-2009.10/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

When I am root OR my login account (cbmeeks), I can:

ruby -v

at the command line and it works.

However, if I:

sudo ruby -v

I get a command not found?

The same is true for any bin in that /opt/ruby-…/bin folder.

sudo works just fine which makes me think the path is not being loaded with SUDO.

I can:

sudo /opt/ruby-enterprise-1.8.7-2009.10/bin/ruby -v

just fine.

Any tips? I've even rebooted the server.

Thanks!
