acl build failure on x86_64

[Jon]

Brandon and anyone else who might be able to shed some light on this 
issue... I'm stumped.

This is a pure 64 bit bootstrap using gcc-4.4.2/glibc-2.11/binutils-2.20 
following Greg Shaffers DIY Linux reference build. I've got almost 300 
packages compiled and am at the tail end of my build so know this has to 
be isolated with ACL.... besides the occasional -fPIC issue with certain 
progs, this is the first stumbling block I've hit.

Thanks for any and all help.
