Anyone else having issues building firefox-6 and thunderbird-6?

Both here fail with errors like this (enormous command lines truncated
for clarity):


x86_64-pc-linux-gnu-g++ -o nsRDFResource.o -c .......
rm -f libxul.so
/usr/bin/python2.7 /var/tmp/portage/www-
client/firefox-6.0/work/mozilla-release/config/pythonpath.py -
I../../config .......
collect2: ld returned 1 exit status
make[5]: *** [libxul.so] Error 1


In both cases the only USE change from default is USE=-system-sqlite.
xulrunner is up to date
MAKEOPTS="-j1" makes no difference
b.g.o has no relevant bugs
google returns nothing of value

I'm thinking it'sa problem specific to my setup but I'm out of ideas
where to look next. Help anyone?
