I am running kernel version: 2.4.0 test 3 pre 2.  I am useing wesolows 
vmlinux-0704b kernel.

I think I have found the problem though.  I was running the system without swap 
and with 64Megs of RAM.  I added around 20 megs of swap space and did the
configure again and it worked fine.  I am actually compiling now and will let 
the status be known if it completes or not.  As of right now everything looks
like it is working fine with the swap enabled.
