current issues:
opencolorio in main homebrew not work in 10.9, this is upstream issue
libvisio cannot build, this is boost 1.55 upstream issue, and libvisio is optional dependency
some other optional dependencies not packaged yet
runtime crash in several callligra apps, this is calligra issues, I will try to fix them but formula is okay since I use git source instead of tarballs.
