Handle clang 3.3 fallout. I wish we had a __FreeBSD_version tag from when the
clang 3.3 import happened, that way we wouldn't have to resort to such hacks.
Rework previous commit. The problem is not clang 3.3 but rather the fact that
with 1000024 CC became 'cc' rather than 'clang'.
Add an explicit build dep on pkgconf
Add an explicit dependency on pkgconf
While here remove the post-patch target in favour of using shebangfix
Downgrade to 2.0802.  Bump PORTEPOCH.

The 2.1001 version was released as a "stable" release by mistake.
Before the real 2.10XX appears, there will be several 2.09XX-TRIAL releases,
which are not meant to be used in production.
