Initial changes to match version updates.
New formulas.
My mktemp is in /bin rather than /usr/bin.
Added ability to download and extract tar.xz files.  Formula must include the xz formula as a dependency since it's not a system command.
Lot's of new and probably broken packages that I forgot to document as well as some changes that include my home directory's path.
Ran along a package that did something with the repo itself.  The way homebrew cloned the repo didn't work, so I manually copy the .git dir over to the staged copy.
Some packages to get CGAL to compile as well as some to get cgal-bindings to work.
Enabled ssl support in svn.
Switched compiler to distcc.
git and expat still had some configurations that where carried over and didn't work on hydra.  Rewrote them.
Added autoconf and automake dependencies to distcc formula so that it can run its autogen script.
Fixed typo.
Added note about bug.
Fixed dependencies for postgis.
Gave up on trying to get distcc to perform well on hydra.
Added some gnu utils. pgsql's docs seem to note that gmake is important, so I make sure it gets that one first.
Postgis requires libxml2.  Make install fails the first time around.
Added coreutils and diffutils formula.
Added some linux from scratch utils.
Had to update some dependencies for imagemagick since they don't retain all previous versions.
