It doesn't ignore that request and was built just fine with Xlib-support
without having GTK2 installed on my system. I have an Athlon 500 and
applications using GTK2 are generally too slow to be really usable,
especially Firefox. Using Xlib instead of GTK2 and disabling XUL made
Firefox quite fast and usable again on my system.

I didn't test GTK1 support.

I thought, there are a lot of people who own a slower system or just
prefer faster browsing experience to some GTK2 eye candy.
My build really works fine and is faster. I don't miss GTK2 a bit.

So I came to the conclusion, that everybody should have the choice
between pretty (GTK2 and XUL) and fast (Xlib without XUL) browsing.

I hope this choice will be included in the port (I don't really care
whether in OPTIONS or with a documented -DVAR flag).
