Yep, you sure can. When I started with NetBSD about half a year ago I 
had only 4MB in my IIcx, but managed to compile perl, xv and a 
current kernel (and several small programs). I had lots of swap space (40MB 
I think) and when compiling the system ran veeeery slowly - You 
definitely don't hang around waiting for compiles to finish, unless you've
got a very good (and long!) book... I think the slowest I got the machine
was when I tried compiling xv and running X at the same time - the machine
didn't panic or anything, but I could hear the system paging constantly. 

I got sick of it very quickly and installed 16MB more ram.
