Insufficient dependencies on www/firefox

[Olaf Seibert]

Hi,

I am trying to upgrade Firefox on a FreeBSD 6 system from Firefox 3.0.x
to the current 3.6.x version.

First there is no way that I have found for portupgrade/portinstall/make
to build the new version before deinstalling the old one, because it is
claimed that the new one has files in common with the old one. Of course
it has, it is an upgrade, just the package names differ. (Portupgrade
wants to upgrade to a newer 3.0.x version, which I don't want)

Next, the dependencies are not correctly recorded. So far, I have run
into nspr and cairo, of which I have apparently old versions. Configure
rejects them, but the minimal version numbers should of course have been
recorded in the port's Makefile. There may be more that I run into
later; every iteration takes a while.

Cheers,
-Olaf.
