this was moved here, right?

i gave it a try in a rather pristine mavericks VM. it almost worked, but the 
build eventually fails at an early stage. here's some first comments and 
questions:

you should add something like

 echo "[url \"git://anongit.kde.org/\"]
 insteadOf = kde:    
 [url \"git at git.kde.org:\"]
 pushInsteadOf = kde:
 " >> ~/.gitconfig

to get git to work (or replace the "kde:" shortcuts in the instructions with 
the actual URLs).

i was a bit suprised to be presented with "Python = C:\ProgramFiles\Python" 
when i ran emerge/kdeenv.sh, this is obviously a windows path. i then diffed 
emerge/kdesettings.ini and emerge/kdesettings.mac and there's only a handful 
of changes between the both. if that is still ok and the python path is 
effectively irrelevant, a note on that would be helpful.

with "emerge kate", i ran into the following warnings and errors after a 
while:

during configuration i get this warning:

<log>
CMake Warning (dev):
  Policy CMP0042 is not set: MACOSX_RPATH is enabled by default.  Run "cmake
  --help-policy CMP0042" for policy details.  Use the cmake_policy command to
  set the policy and suppress this warning.

  MACOSX_RPATH is not specified for the following targets:

   KF5CoreAddons

This warning is for project developers.  Use -Wno-dev to suppress it.
</log>

is this related? is there something i could try to fix this?
