Porting TalkFFI / LibClang to Pharo 5 UFFI

Looks like I've been reinventing the wheel making an FFI interface to libclang.  I just bumped into Ciprian's TalkFFI which provides a NativeBoost interface to libclang (and was used to create libgit2 bindings)

But it is NativeBoost based and the Configuration loads AsmJit and NativeBoost packages, which seems to lock up while "Initializing Nativeboost."  What is involved in porting TalkFFI to Pharo 5.0 UFFI?

For a start, these can be manually load no problem... 

  LibClang-FFI-Types-CiprianTeodorov.2 

  LibClang-Tests-CiprianTeodorov.5

  LibClang-Examples-CiprianTeodorov.2

but loading LibClang-FFI-Binding-CiprianTeodorov.1

reports "This package depends on the following classes:

  CLLibraryMap

  CLExternalLibraryWrapper

You must resolve these dependencies before you will be able to load these definitions: 

  CXIndexH"

which I found these in TalkFFI-Runtime-CiprianTeodorov.7, but loading this

reports "This package depends on the following classes:

  NBExternalLibraryWrapper

You must resolve these dependencies before you will be able to load these definitions: 

  CLExternalLibraryWrapper

which I see is in Pharo 4.0 and not Pharo 5.0.  So what is the replacement for NBExternalLibraryWrapper?

What are the other general patterns for porting NativeBoost apps to UFFI?
