mplayer-plugin and xulrunner problem

[Lasse Hillerøe Petersen <lhp%toft-hp.dk@localhost>]

Hello!

Yesterday I started a fresh build of some packages, using pkgsrc-HEAD.
However, mplayer-plugin can't compile, apparantly because xulrunner no longer
provides some stuff. The file it complains about missing is jri.h.

While searching for whether this is a known bug, I came upon very little,
except for one file: 
http://ftp.netbsd.org/pub/pkgsrc/misc/joerg/20100325.0024/mplayer-plugin-3.55nb1/build.log
which has the same build log.

Any suggestions as to how I can get around this?
