mozilla-devel compile fails

[walt]

The build halts during or right after the patches are being applied.

The problem is that sed can't find this file:
47635 sed      NAMI 
"/usr/ports/www/mozilla-devel/work/mozilla/build/unix/mozilla-gtkmozembed-devel.pc.in"
  47635 sed      RET   lstat -1 errno 2 No such file or directory

In fact the real name of the file is mozilla-gtkmozembed.pc.in, and I
haven't been able to figure out yet why sed is looking for the wrong
filename.  Why does the extra "-devel" get stuck in the middle of the
filename?  Dunno.

BTW this is on -STABLE -- haven't yet tried it on -CURRENT.
