opencv-2.0.0 Can't read "build.cmd"

[matthew.barulic@…]

While attempting to install 'opencv' on Mac OS X v10.6.3, using

sudo port install opencv

the following error was returned

--->  Computing dependencies for opencvError: Unable to execute port: can't read "build.cmd": Failed to locate 'make' in path: '/opt/local/bin:/opt/local/sbin:/bin:/sbin:/usr/bin:/usr/sbin' or at its MacPorts configuration time location, did you move it?

You haven't installed Xcode (or haven't installed it properly). See the FAQ entry.

Thank you! I had installed Xcode earlier, for another project and had not added the necessary extensions. However, now I'm presented with a new error,

When I try to install some of the dependencies on their own, i get a similar error.

That's a totally different error now, and looks exactly like #24599. I never did find out why it happened, but the user in that ticket said cleaning zlib was all he needed. Can you try that?

sudo port clean zlib

Thank you very much! That one line fixed it up. Sorry for my misuse of the system, I'm just now figuring it out. Thanks again for your help.
