Well it's not just GNOME. Imagine you installed php on your server and
few weeks later you want to quickly add one extension, but now you have
php 4.4.1 and added extension is from php 4.4.2 -- you have to rebuild
all php too.

This looks like a larger design problem and I don't know from where to
start attacking it.

I think the opposite - perhaps it's because you're not reading all the
support questions gnome@ receives.

Oh no, we can't just let rely on configure checks. First, we never want
`make` to fail. Than we could go Slackware and forget the dependencies
in ports anyway.

Second, endusers just can't read configure output. Configure script
tells them they have outdated fontconfig and you know what people do?
They copy&paste that message and ask for help for it.

That would do - but it can't happen overnight, the ports are just too
many to go see every single one's configure script...

You don't have to have USE_GNOME=libgsf in your port at all...
