Linphone (3.9.1) compiling error with ./prepare.py --package in OS X El Capitan (10.11.4)

I had clone the linphone-desktop project and follow all the steps provided both on the README and in the README.macos from the linphone repository to install all the dependencies, by the way I'm using MacPorts 2.3.4. So, I have an error compiling after I ran the prepare.py script with the --package option. But the thing is that when I ran the prepare.py script without the --package option and compile again it works just fine. Output from iTerm: Install the project... -- Install configuration: "Release" Cannot find source to copy: /Users/pvaldivieso/Downloads/linphone-desktop/OUTPUT/lib/mediastreamer/plugins/*.*.dylib error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/install_name_tool: can't open file: /Users/pvaldivieso/Downloads/linphone-desktop/WORK/PACKAGE/Linphone.app/Contents/MacOS/Linphone-bin (No such file or directory) /usr/bin/patch: **** Can't find file /Users/pvaldivieso/Downloads/linphone-desktop/WORK/PACKAGE/Linphone.app/Contents/Resources/share/themes/Quartz/gtk-2.0/gtkrc : No such file or directory pkgbuild: error: Component path "/Users/pvaldivieso/Downloads/linphone-desktop/WORK/PACKAGE/Linphone.app" does not exist. [100%] Completed 'TARGET_linphone_package' [100%] Built target TARGET_linphone_package It goes all the way to the end and fails. I think it's related to mediastreamer and not finding some .dylib but I'm not sure. My question is: how to generate the installation package for Mac OS X?
