Thomas, 

Might the current hg compile with fltk-aqua 1.1.7-1001? ... or is 1.1.9 
required? ... perhaps fltk-aqua won't work either and I'll need fltk-x11?

If fltk-aqua 1.1.7-1001 is all that is needed, it should be a fairly simple 
task to get the current hg version working using Fink for the dependencies.
