------------------------+----------------------
 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)

 current version 2.1.0)

 (compatibility version 1.0.0, current version 22.0.0)
         /System/Library/Frameworks/Python.framework/Versions/2.7/Python

 version 307.5.0)
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
 version 1238.60.2)

 }}}

 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:

 }}}

 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.
