The error is in linking libjawt.so. There are references to undefined 
symbols - see below.

And yes I meant libmawt not libxawt - sorry about that, got confused 
between the library name and the directory it can be found in.

AFAICS the missing symbols are in libmawt, which is specified with 
-lmawt but I couldn't see where it would be found. However you've now 
told me it should be in headless (which is set by -L) - and there it is, 
but the symbols are not in there - so I think my problem is that 
headless/libmawt.so is not being built right, and that is something I 
can link to my Makefile changes!

Many thanks!

David
