[Vortex] PATCH: Search-path initialization for OS X framework

[Francis Brosnan Blazquez]

Hi Jens,

Because finding DTD at the initialization of vortex seems to be a common
issue that causes some headache, I've updated vortex library (both
branches) to include a C inline representation from DTD used. See [1]. 

In any case thanks for reporting Jens. Cheers!
