Correct.

I'm not sure how to handle this situation, but if firefox3 really depends
on cups support in gtk, then it shouldn't try to load the cups library if
gtk is not build with cups support.

Where I would prefer not to rebuild gtk to get cups support for firefox3.
firefox2 works fine for printing with cups and gtk without cups support.
It is easier to enable the cups option and rebuild a leaf package afterwards
if it is not the default option.
