I realised that -msse4.1 and -msse4.2 aren't supported by GCC 4.0, so I made
the brash decision that we require GCC 4.2. It comes with Xcode 3.1 so people
can upgrade if they have to.
Requiring a single compiler is better for us anyway -- less possible errors
and failures.
Formulae can still request gcc-4.0.1, but at least then those formulae still
only use a single compiler and not possibly two.
This regards Issue Homebrew/homebrew#30.
Turns out -march=native isn't supported by Apple's GCC, but while investigating it I found they'd back ported the -march=core2 option, so we win anyway.
Logic reverted to how it was yesterday.
I moved the gcc options stuff back to brewkit.rb as we manipulate the cflags more later and it seemed bad form to split the logic for this area over two files.
Additionally the brew command exits immediately on powerpc now. Brewkit doesn't throw as theoretically it is a useful library file for other projects.
If brew is called with an explicit path, eg. './bin/brew',
HOMEBREW_PREFIX is set to an empty string resulting in failure of all
brew commands using HOMEBREW_PREFIX. This commit forces Pathname to
compile an absolute path, setting HOMEBREW_PREFIX correctly.
Specifying -v/--verbose shows the build environment before the build
MACOS_VERSION contains the floating point value of the OS X version

I removed the Dir.chdir line altogether as it was a hacky solution to an issue
in Ruby that I encountered a lot during early development, ie. I'd brew rm
while working directory was set to that keg.
Because we modified the ENV global each install this propagated to consecutive
formulae. So exec a new brew process each install. This is the safest way
although Ruby exceptions don't propagate to the parent process so I worry
about it somewhat.
Large refactor to Formula, mostly improving reliability and error handling but
also layout and readability.
General improvements so testing can be more complete.
Patches are automatically downloaded and applied for Formula that return a
list of urls from Formula::patches.
Split out the brew command logic to facilitate testing.
Facility from Adam Vandenberg to allow selective cleaning of files, added
because Python doesn't work when stripped.
I keep breaking this stuff, need more tests, and well I think it's due to
developing on multiple machines and having different states of checkouts. So
apologies, I'll FIX myself too :)
