lemon: Added patch (see https://lemon.cs.elte.hu/trac/lemon/attachment/ticket/480/51deaff8728a.patch Ticket #480).
pyqt4: Added a new patch to fix build errors with PyQt4 looking for phonon.
openblas: Added TARGET=SANDYBRIDGE. According to their change log ( http://www.openblas.net/Changelog.txt ). This should support Haswell and thus Crystalwell as well. Note the list of supported targets ( https://github.com/xianyi/OpenBLAS/blob/develop/TargetList.txt ) does not explicitly include Haswell or Crystalwell.
Qt4: On Mavericks the Xarch_x86_64 flag is not appropriate as the OS only supports 64 bit systems. However, Qt4 uses this flag in a way that is no longer compatiable on Mavericks. As a result, this causes Qt4 to fail to build. This commit comments out lines using those flags and simply adds the exact same line below with two patches that are applied. It may be worthwhile to actually create small pieces of code to test for Mavericks in particular so as not to break the build for other OSes.. However, this has not been done in this commit.
sip: Corrected cmake file so that additional flags (-b, -d, -e, -v) are uncommented. They must be uncommented for the build to work. Otherwise, the build will fail to use the correct SIP and may use a system installed SIP. This will affect whether building qimage2ndarray succeeds or fails.
qt4: Was using PATCH_EXE defined in PatchSupport, but had the include of  PatchSupport commented. This line has been uncommented and a comment to this effect was left.
nose: The URL for external_source contained the file to download, which it shouldn't. This caused build errors.
qimage2ndarray: Removed PatchSupport comment as no patching is happening here. Also, added SHA1 commented for the release in question.
gmp: Added more detail to comment at top about the cmake file. Removed extra quote in CONFIGURE_COMMAND that was causing build errors.
mpfr: Added more detailed introductor comment. Added an additional flag to the configure comment to help specify where gmp is just for clarity.
python: Added a patch to stop the buildem Python from including the system Python packages in sys.path for Mac. Without this patch, buildem Python may fail to install packages and use system versions instead of buildem versions or in the worse case link against system Python libraries/packages instead of buildem version.
mpfr: Link used for downloading mpfr  no longer works. Added a new one that does work. Verified that the md5 is a match.
openblas: Replaced head by working commit. Removed TARGET specification (seems to be working without it).
README_openblas: Added README to for openblas to explain TARGET specification and point to further information.
README_openblas: Added more details about default TARGET (NEHALEM) and a link to a list of architectures options for TARGET in the OpenBLAS repo. Broke up the contents a nicer more reader friendly way.
vtk: Forced manual reference counting as garbage collection is deprecated and VTK has not fully implemented automatic reference counting.
vtk: Added note about VTK 5 not supporting automatic reference counting.
