I'm not happy about bumping every shared lib. Can you answer:
(1) does a ``make world'' will not work? Peter showed that we had no
choice with libc due to the use of the host's existing install programs.
(2) even if #1 works, will a 6mo. old binary (using one of these libs)
run w/o the change? Will a binary from 4.2-R run?
If this is just to keep one from having to reintall /usr/local/, I'm not
sure that is suffient reason for the bumpage.
Note that if you are going to bump shlib versions, you should follow the
libc.so versioning scheme.
