Yeah. Just something to build the binaries should work.

Nice. Apache I know you could fit into that without a problem, and X
should be able to handle that little

Look up ALFS (Automated Linuc From Scratch). It's a basic system, but if
you want something fairly minimal, I'd suggest looking at Portage and
the ebuilds you like and see if you couldn't script yourself a small
package manager just using wget and maybe doing the compiling by hand
(or just running ./configure && make && make install, if you don't want
to do anything to minimize the installed packages).
