[Paparazzi-devel] Why I can't install paparazzi on my macbook?

[心如烛光]

    HI,everybody.I have a trouble about installing paparazzi on my macbook pro with OSX lion(ver 10.7.3).First I installed the newest Xcode(ver4.3) and the newest macports(ver2.0.4). Then I followed wiki's instructions step by step.

But warnings and errors occurred  after I typed "sudo port install paparazzi".

It said:"Warning: The Command Line Tools for Xcode don't appear to be installed; most ports will likely fail to build.

Warning: See http://guide.macports.org/chunked/installing.xcode.html for more information.

--->  Computing dependencies for paparazzi-tools

Error: Dependency 'ocaml' not found.

Error: Status 1 encountered during processing.
