If you use portupgrade(1) and you don't use the '-u' flag, then a copy
of any shlib owned by a port will be preserved in
/usr/local/lib/compat/pkg/.  That directory is added to the standard
ldconfig path by the 000.pkgtools.sh startup script which comes with
portupgrade.  All in all, that means that programs depending on
outmoded shared libraries should still work and restart correctly.

Eventually you should update all software that depends on the updated
shlib, but that can be quite hard to do.  The sysutils/libchk port
will help you do that, as will following instructions to run
'portupgrade -rf' and, something which seems to be happening more
frequently now, maintainers bumping the PORTREVISION number on their
ports if the port links against a shlib that has been updated.

Together all those measures should smooth over most of the problems
you might run into.

	Cheers,

	Matthew
