NeXTstep 3.3 minimal developer setup

I'm looking into ways of setting up a "poor mans 3.3 developer toolkit" up on a NeXT slab which currently has 3.3 user installed on a 100Mb hard disk. Before I get too into the idea I thought I'd better ask if anyone on the list has already tried and failed :-) I'm guessing that all I *really* need are the includes - the libraries are already installed, and IIRC I can cross-compile GNU tools on a Linux box (any idea what versions of compiler etc were supplied with 3.3 Developer?). I'm happy to archive apps to floppy to free up a bit more space if required. Any thoughts, NeXT fans on the list? I know it's probably easier to trawl for a copy of 3.3 Developer and just install a bigger hard disk, but this way seems a bit more fun :-) TIA Al.
