You were right!  I managed to find another 32MB of memory to bump it up to 64
MB total and it worked perfectly.  It appears that I had only about 4 MB of
buffer/cache in the 48 MB system and over 15MB in the 64 MB system.  I did my
install and switched back to the 48MB running normally and its working just
fine.
