Subject: load path

Hi,

I've discovered that the load path is different if I run sudo, specifically it doesn't pick up the value in GEM_HOME, even though `sudo echo $GEM_HOME` shows the correct path. Everything else I've checked between sudo/not has been identical, so I was wondering where the load path is originally set or when it's first picked up? 

I'm running ruby v1.9.2 on OSX 10.6. All the info below is identical, except for the missing path in $: in `sudo irb`

echo $GEM_HOME
/Users/iainuser/.gems

sudo echo $GEM_HOME
/Users/iainuser/.gems

irb
puts $:
.
