I think I see the problem (although I have not really looked at LFS). 
mp1e writes to stdout.  The shell (i.e. bash/tcsh/etc.) actually writes
to disk.  Make sure that your shell is compiled with 64 bit support.

A simple test would be "dd if=/dev/zero of=junkfile bs=1M count=3M" and
see what file size you get - if it is only 2G, then it is likely the
shell causing your problems??
