configure: error: xpidl compiler not found

Hi,
I am trying to compile gecko-mplayer from svn sources, but I get a
configure error. Any tip on how to solve this ?

This is the error message:

./configure
....
....
checking for pkg-config... /usr/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
checking for GLIB... yes
checking for GECKO... no
configure: WARNING: mozilla-plugin not found, trying another
checking for GECKO... yes
checking for xpidl... no
configure: error: xpidl compiler not found


Some info where xpidl is in my system:

e@nFs-desktop:~/apps/gecko-mediaplayer$ locate xpidl
/usr/lib/firefox/xpidl
/usr/lib/xulrunner/xpidl
/usr/lib/xulrunner/sdk/bin/xpidl
/usr/lib/xulrunner-1.9b5/xpidl

This is on Ubuntu Hardy 64bit, and both Mplayer and gnome-mplayer
works fine on this box.

Regards
