JS now defaults to the POSIX-based NSPR emulation layer on Linux and OSX. It looks like ctypes uses some scary NSPR stuff that we don't have emulation for. From a quick scan, I see:

  PR_LoadLibraryWithFlags
  PR_UnloadLibrary
  PR_FindFunctionSymbol
  PR_FindSymbol

We'll need to either implement these (and associated types), or change the default NSPR mechanism when --enable-ctypes is given, or both one at a time.
