Just for info, on my 64-bit system I just updated Portage w/o any problem:
root:525 etc> equery belongs /usr/bin/quickpkg
[ Searching for file(s) /usr/bin/quickpkg in *... ]
sys-apps/portage-2.1.9.24 (/usr/bin/quickpkg ->
../lib64/portage/bin/quickpkg)
root:526 etc> ls -l /usr/bin/quickpkg
lrwxrwxrwx 1 root root 29 2010-11-27 14:23 /usr/bin/quickpkg ->
../lib64/portage/bin/quickpkg
root:527 etc> equery belongs /usr/lib64/portage/bin/quickpkg
[ Searching for file(s) /usr/lib64/portage/bin/quickpkg in *... ]
sys-apps/portage-2.1.9.24 (/usr/lib64/portage/bin/quickpkg)
root:528 etc> ls -l /usr/lib64/portage/bin/quickpkg
-rwxr-xr-x 1 root root 9224 2010-11-27 14:23 /usr/lib64/portage/bin/quickpkg
I've never set 'collision-protect' in make.conf ,
but have never run into a problem as a result.
