>Description:
mozilla 1.7 from pkgsrc doesn't work on amd64.
It seems to be due to a -fPIC related gcc bug.
See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16092 for details.
>How-To-Repeat:
cd /usr/pkgsrc/www/mozilla
make install
mozilla
>Fix:
The following patch from the gcc bugzilla seems to work.
