Well, if the "old" libc (that'd be libc.so.4) can't read the "new" format, and 
there'll be no "old" format, then the answer is NO, actually. Almost none of 
the freebsd-4 binary packages will work, because of locale info being now 
used everywhere.

Can't the sources producing libc.so.4 be made to call the sources producing 
libc.so.5, or what?
