I get errors when trying to install GTK+3 on my Mac OSX 10.9 system I'm trying to install GTK+3 on my Mac OSX 10.9 system to run a pyGObject project I've been developing in Ubuntu. It runs perfectly on Ubuntu, so I wanted to test cross-platform compatibility. I'm following the directions on wiki.gnome.org.

I finished the part where I run the sh gtk-osx-build-setup.sh command. It loads everything perfectly (as far as I can tell). However, if I do a which jhbuild or try a command, I get an error:

EnvironmentError: MacOSX10.9.sdk not found
jhbuild: could not load config file 


Any suggestions on how to fix this and finish installing jhbuild? It seems like the instructions from their webpage are a little incomplete or perhaps I'm not adding to path correctly?

Questions:


Which file do I put the path? Is it .bashrc or .bash_profile (neither have worked so far). Perhaps some other file is my bash profile script?
What is the path to the jhbuild? In the example, it says alias jhbuild="PATH=gtk-prefix/bin:$PATH jhbuild", but I'm not actually sure what I should substitute in for gtk-prefix (not sure where the actual path is, since which jhbuild doesn't work).
Forgive me if this is a silly question but do you have Xcode installed?

The OSX SDK should be installed on your system within the Xcode application bundle. You should be able to find it at /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/.

If Xcode isn't installed you can install it for free from here.
