[Rainer Hurling]

According to PR 141131 I see exactly the same error messages when I try 
to upgrade from libxul-1.9.0.15 to libxul-1.9.0.16:

-----------------------------------

This happens on three different machines all running latest 9.0-CURRENT 
(i386). As far as I can see there are no relevant flags set in 
etc/make.conf.

Any clues what is going wrong? I found no solution to this PR.

Please let me know if I can provide more information or test something.

Many thanks in advance,
Rainer Hurling
