It looks like OpenGTL is going to be the sticking point,

upstream appears dead, and llvm removed its old school llvm::sys::Path interface
that OpenGTL appears to use in a few places. My C++ is fairly fail, and I managed
to at least fix two files, but then realised how big a hole I was digging.

If anyone has some C++ expertise (package maintainer cc'ed), and some time it might not
be too bad too work out,

Dave.
