Hooray! This is now a part of the main Homebrew, so curling my parts is not necessary. This means (assuming the homebrew executable install location is in your PATH) Synfig is installable on a Mac like so:
brew install etl
brew install synfig
The synfigstudio package is called `synfigstudio` and is the only part remaining to be pulled into the main Git repository. Because Homebrew is better than Fink in many ways, the Fink package links can be changed to the Homebrew ones as soon as synfigstudio is pulled. The Homebrew formula is also up to date and installs flawlessly. Although Homebrew can only run graphical interfaces in X11 at the moment, it can be made into a .app bundle I think. However, an X11 bundle would not be ideal as it does not integrate well. As I saw someone say on http://nextsprocket.com/tasks/native-no ... r-homebrew
I think the XML format that jhbuild uses may be translatable into Homebrew stuff; most of the bundlers etc are built w/ autotools or cmake, from tarballs or git repos. So, hopefully, jhbuild can be eliminated from the build process and Homebrew can be used for everything.
This will make the build process a whole lot simpler.
