subprocess.CalledProcessError while installing on OSX

edit

I'm getting this error while installing electric on Mac OSX 10.7 Lion. Any help would be appreciated. Thanks.

I think I've tried this patch but no good. CMakeLists.txt I used is here. However, I concern what wjwwood says in this page (copied below). This sounds like the patch can solve the issue but it doesn't work for me:

The latest patch, ros_comm-1.6.5-rosconsole_g++-4.2.patch, has not been released. With completely up-to-date Xcode installs this will cause a failure when compiling rosconsole as g++-4.2 no longer exists.

I have tested the new patch, I think it needs to be applied so it can be in the next release.
