ah, I think the issue with the static load is that the executable is a
python script...

I see I have way too many pythons installed for comfort:

$ pkg info | grep python
py27-goocanvas-0.14.1_5        GooCanvas python bindings
python-2.7_2,2                 The "meta-port" for the default version of Python interpreter
python2-2_3                    The "meta-port" for version 2 of the Python interpreter
python27-2.7.8_4               Interpreted object-oriented programming language

This may be a result of doing some incremental builds of ports, rather than
everything all at once; or not.  If the above should not normally all be
installed at once, is there an easy way to determine which ports need to be
rebuilt?  The openshot script runs python2.7 which was installed by the 
2.7.8_4 package, but some library it uses may well have been installed by
one of the earlier versions.
