Upgrading from GTK 2.4.x to 2.6.7 recently broke Firefox on my system, so I
decided to rebuild from pkgsrc. Unfortunately, the build fails when
"nsIDOMParser.h" is not found. This file does not exist at all. I recently built
Firefox 1.0.2 on another Linux machine using pkgsrc, so I've reason to believe
this is a Firefox bug and not pkgsrc-related, but I figured I'd ask here first.

There is a file called "nsIDOMParser.idl" Is this a file that needs to be
preprocessed, but isn't getting done?

Here is the offending error:
