I've been working on a set of changes to get it to build.  There were 
actually many more changes needed but I already committed them.  I left 
the hash table changes out because I'm planning to switch over to use 
the hash table code from Utilities/kwsys.  Attached is the patch to 
apply to make the switch now.  I'll commit the changes after more testing.
