install Apache1 and Apache2 on the same server

[Ksenia Marasanova]

Greetings,

I have FreeBSD box that runs Apache1 from ports. Now I'd like to
install Apache2 from ports (and run it on different IP), without
overwriting httpd binary of Apache1. What would be the correct,
port-friendly :) way to do it? (I also use portupgrade, it would be
nice if portupgrade will still be able to upgrade both ports)

Any tips or pointers to man pages are appreciated.

Thanks!
