Pangolin @0.5: Opportunistic use of many libraries

[ryandesign (Ryan Carsten Schmidt)]

Pangolin opportunistically uses many libraries. In the archive produced on our buildbot (where there are no ports active other than those the portfile declares as dependencies), the library links as follows:

$ otool -L /opt/local/lib/libpangolin.dylib
/opt/local/lib/libpangolin.dylib:
	/opt/local/lib/libpangolin.dylib (compatibility version 0.0.0, current version 0.0.0)
	/System/Library/Frameworks/OpenGL.framework/Versions/A/OpenGL (compatibility version 1.0.0, current version 1.0.0)
	/opt/local/lib/libGLEW.2.1.0.dylib (compatibility version 2.1.0, current version 2.1.0)
	/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa (compatibility version 1.0.0, current version 22.0.0)
	/System/Library/Frameworks/Python.framework/Versions/2.7/Python (compatibility version 2.7.0, current version 2.7.10)
	/usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 307.5.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1238.60.2)
	/System/Library/Frameworks/AppKit.framework/Versions/C/AppKit (compatibility version 45.0.0, current version 1504.83.101)
	/System/Library/Frameworks/ApplicationServices.framework/Versions/A/ApplicationServices (compatibility version 1.0.0, current version 48.0.0)
	/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 1349.90.0)
	/System/Library/Frameworks/CoreGraphics.framework/Versions/A/CoreGraphics (compatibility version 64.0.0, current version 1070.22.0)
	/System/Library/Frameworks/Foundation.framework/Versions/C/Foundation (compatibility version 300.0.0, current version 1349.91.0)
	/usr/lib/libobjc.A.dylib (compatibility version 1.0.0, current version 228.0.0)

But if I build it from source on my own system, where I have lots of other libraries installed, it links with a lot more things:

$ otool -L /opt/local/lib/libpangolin.dylib

	/usr/lib/libobjc.A.dylib (compatibility version 1.0.0, current version 228.0.0)

For each thing that it's linking with that's not declared as a dependency in the port, the port needs to either declare that dependency or instruct the build system not to use that thing.
