Finally got some time to actually try it.  Error in python vdigit -  
it's looking for geos_c.h, from Vect.h.

For the linking, it works on OSX as is, but only because I include  
both C++ and C APIs (libgeos and libgeos_c) in the same binary in the  
GEOS framework.  On other platforms, libgeos_c is probably necessary.

Theory of the Universe

There is a theory which states that if ever anyone discovers exactly  
what the universe is for and why it is here, it will instantly  
disappear and be replaced by something even more bizarrely  
inexplicable.  There is another theory which states that this has  
already happened.
