"export CC=/usr/bin/gcc-4.x" where x is the version you want to use for 
the package you are compiling.

For 4gb+ on an x86 system, you want a pae enabled kernel. I don't know 
how 32bit Ubuntu does it, but I'd imagine their linux-image package has 
a server version that has pae extensions compiled in.
