REE and ruby PATH problem

Rails
1

I have ruby normal edition installed in /usr/bin
REE in /opt/ruby-enterprise-1.8.7-2010.01/bin
I have all my application gems installed in /opt/ruby-
enterprise-1.8.7-2010.01/bin
but still when i run any gem related command, say “sudo bluepill
status”, it looks for the executable in normal ruby edition instead of
REE

Any ideas?

ubuntu > echo $PATH
/opt/ruby-enterprise-1.8.7-2010.01/bin
/usr/local/sphinx/bin
/usr/local/sbin
/usr/local/bin
/usr/sbin
/usr/bin
/sbin
/bin

ubuntu > bluepill
You must run bluepill as root.

ubuntu > sudo bluepill status
sudo: bluepill: command not found

ubuntu > which bluepill
bluepill is /opt/ruby-enterprise-1.8.7-2010.01/bin/bluepill

ubuntu > whereis bluepill
bluepill: /opt/ruby-enterprise-1.8.7-2010.01/bin/bluepill

ubuntu > ruby -v

Also notice that the gem environment does not reflect the REE version
of Ruby,

RUBY VERSION: 1.8.7 (2009-12-24 patchlevel 248) [x86_64-linux]

sudo will set up its own environment (including its own PATH). You
should be able to set things up so that it includes /opt/ruby-
enterprise-1.8.7-2010.01/bin though

sudo /opt/ruby-enterprise-1.8.7-2010.01/bin/bluepill

maybe sudo echo $PATH

ubuntu > whereis gem
gem: /usr/bin/gem1.8 /usr/bin/gem /opt/ruby-enterprise-1.8.7-2010.01/
bin/gem

As Ivan suggested, i think its a rubygems problem. I havent installed
rubygems in the REE. Currently it is installed only in normal ruby.
I will install rubygems in REE and uninstall from normal ruby and then
check. Basically keeping only REE.

try check
sudo echo $PATH
sudo which bluepill

The REE installer installs rubygems for you (and your whereis output
shows that)
