All of them

use aptitude, and select the development stuff, it'll solve all the dependencies and put them all back on. Its how I removed them in the first place

NOW that being said, I KEPT that system image. Its 1 gig download, decompress and flash. I have not posted it online because I had the fear i'd get hammered with bandwidth.
I'm looking at releasing that image or building two versions of PlugPBX, one with dev tools pre-installed, one without, so users could just compile what they need on the Plug.
I'm still waiting for my third sheevaplug (allocated for dev and testing work) to arrive and I can follow up on these plans..
If anyone wants to mirror the 'dev' version I'd be happy to make the disk image available sooner - you'd have all the sources etc I compiled from!
Anyone interested in this?
