I use FreeBSD 8.4-RELEASE-p4 i386.
According to /usr/ports/UPDATING 20131008, I use
FAVORITE_COMPILER=gcc
in /etc/make.conf - then chromium is attempted to be built using GCC 4.7,
but chromium build fails, though later - on some step 5xxx/12xxx.

Which last version of Chromium did you build and use successfully?

Fresh Chromium 31.0.1650.63 built with clang doesn't work for me
(doesn't render www.yahoo.com and groups.yahoo.com).
Package
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-8-stable/All/chromium-28.0.1500.95.tbz
installed with pkg_add (I don't use pkgng) seems to work somewhat better.
I use Firefox, I'm trying to only test a broken website (groups.yahoo.com)
in Chromium.
