ruby gem path

[Thufir]

Do I need to manually set path info for each gem?

thufir at ARRAKIS:~/rb$ 
thufir at ARRAKIS:~/rb$ sudo gem install --remote rake
[sudo] password for thufir: 
Successfully installed rake-0.8.7
1 gem installed

thufir at ARRAKIS:~/rb$ rake --tasks

thufir at ARRAKIS:~/rb$ 
thufir at ARRAKIS:~/rb$ cat /etc/lsb-release

DISTRIB_RELEASE=9.04
DISTRIB_CODENAME=jaunty
DISTRIB_DESCRIPTION="Ubuntu 9.04"

thufir at ARRAKIS:~/rb$ 


Of course, this particular gem can be installed from apt-get, but 
shouldn't it be handled by gem?
