firefox build failure

[Nikita Ronja Gillmann <nikita%netbsd.org@localhost>]

I'm getting the error below in pbulk on NetBSD amd64 10.99.10.
I'm considering rebuilding all the packages to see if something failed 
to build correctly, or just start with a new cvs checkout (I already 
cleaned it up enough before this)..
Has anyone run into this before?
