Hmm, tried to install in Ubtuntu. Got:
~$ aptitude install build-essential python-dev python-twisted python-bsddb3
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
Dumb question, but do I need to be root to install? Just use sudo before "aptitude"? Always makes me nervous to install this stuff when I am not sure what Im doing.
