#37530: OpenCV 2.4.3 fails to build on fresh install of Mountain Lion
------------------------+--------------------------------
 Reporter:  macports@…  |      Owner:  macports-tickets@…
     Type:  defect      |     Status:  new
 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.1.2
 Keywords:              |       Port:  opencv
------------------------+--------------------------------
 I'm on a freshly installed Mountain Lion with all current updates
 installed (Mac OS X 10.8.2), including a current XCode with Unix
 commandline tools (i.e. clang, etc) installed. I've installed MacPorts
 from the *.mpkg binary installer, issued "sudo port selfupdate" and
 installed just three packages (automake, autoconf, libtool) and then tried
 to install opencv including the Python 2.7 wrappers.

 "sudo port install opencv +python27" fetched all dependencies, downloaded
 and extracted the OpenCV tarball, but failed configuring it. The error is
 (see attached logfile) stated below. Cleaning and trying again did result
 in an identical error.

 A short web search resulted in the info that this might be due to a broken
 cmake. This is what I found:[[BR]]
