Mavericks problems
I wasn't sure whether to add it to issues, but on Mavericks vim build will fail with "conflicting types for 'sigaltstack' " error. After some googling, apparently for now the solution is to inclue "AvailabilityMacros.h" header in os_unix.c.
Also, the project depends on XQuartz.
It's possible that just updating the vim source will work. I can put that on a branch for you to test, if you like.
I'm not sure about the XQuartz part... I tried to disable all X dependencies. Any idea which component(s) need it?
I think I tried the latest source and the issue was still there. X11 includes were needed by ruby. Perhaps there are alternative includes already on os that aren't in my search path?
Also, I had to add "execute pathogen#infect()" to vimrc to get plugins to work, which is expected I guess, but for plugin noobs like me, it should say explicitly in the instructions ;)
