I do not think this is a Repository issue but a package system issue. 
Perhaps what we should revisit is chroot approaches to building packages 
or maybe using fakeroot to at least limit the damage. After all, sooner 
or later, someone, by error or otherwise, will do something like this. 
however protecting people from themselves introduces complexity that 
most don't want, so...

Unfortunately, mount -r --bind /lib lib didn't seem to work, well, just 
an idea.
