[Rails] rake task can't find installed gems

I'm running a rake task and it complains there are "Missing gems" even
though they are indeed installed. However from further inspection, it
appears it is not looking in my GEM PATH (/usr/local/lib/ruby/1.8) but
instead is looking in

/usr/lib/ruby/gems/1.8.

my gem env:
RubyGems Environment:
- RUBYGEMS VERSION: 1.3.7
- RUBY VERSION: 1.8.7 (2010-04-19 patchlevel 253) [x86_64-linux]
