Hello
On my (Ubuntu Linux 12.04, gcc-4.6, pkgsrc-2012Q2), I noticed that many
many programms, but not all, where trying to force me to boostrap gcc-3
although I had a perfectly working compiler.
I pinpointed the problem to all makefiles which contains
"../../mk/compiler.mk"
After some research I found this mail
http://mail-index.netbsd.org/pkgsrc-users/2009/07/30/msg010316.html
which mentions setting LC_ALL=C.
I did that and suddenly pkgsrc started to use my system compiler.
Posting here in case somehow is hit as well.
