And while looking at this and being confused, I noticed this...
(this is grepping for libGrantlee_Templates.5.dylib in the dtruss output)

So it finds and opens the shared lib successfully - and then looks for it all

So my summary so far - it finds the shared library and the plugins, but it
doesn't feel like using them for some reason?
