We can change it from a configure/compile-time error, to a run-time ?

Considering there are not very many ports that use extended regexps
anyway, it can be made to just error out when doing a -E reinplace...
(rules of the game being that using jaguar *and* extended won't work)
Alternatively one could just use an older MacPorts version for Jaguar.

But add a ticket for it, and I'll take a peek at hacking something up.
