mozilla build question

[Hendrik Visage]

Hi there,

on http://www.mozilla.org/build/unix-details.html:

libIDL 0.6.3 - 0.6.8
Source snapshots are available from Mozilla via ftp. If using the RPMs, you'll need both the regular rpm and the -devel rpm.
If you already have ORBit installed, then you do not need to install libIDL as ORBit bundles libIDL. You man need to install the ORBit-devel package if you use packages.

But mozilla's depends have libIDL (version 0.8.0), and that 
depends on gtk+-2 & glib-2.

Mozilla at present are the most gtk+-2/gnome2 loving application (afaik)
and the question then comes up:

 Why libIDL dependency?
(It doesn't appear to fail at present with a
 test DEPENDS with libIDL & gtk+-2 stuff commented out)
