Lots of bug fixes and a new sequence menu.
The configuration is changed to allow the creation of a distibutable
package (before, the port relied on the local domain name as
discovered at configuration time). Now there is no default domain ...
i.e. the MTA should fully qualify addresses (as god intended).
At one point bsd.port.mk put out erroneous PLIST-auto, with @cwd, @pkgname,
and @pkgdep lines.
These are actually added by make package, and shouldn't usually be put
inside the PLIST, as this is extra information to update.
I left a few @cwd in, mainly for the perl modules, which want to live under
/usr to work.
