Well, I don't see any point in setting CC there. I had to remove the line to 
bootsrap pkgsrc on PowerMac G5 with GCC-4.2.1.

You'll see "cc", but "clang" will be called by a wrapper. You can see it in 
work/.wrapper/bin/cc:
cmd="/usr/pkg/bin/clang"
And, sometimes, you'll notice colourful clang warnings. ;)
