Trying to build my app with DMD2.66 and GtkD 2.4.2

[Steve Teale via Digitalmars-d]

I'm trying to build my app after upgrading to DMD2.66 and the 
latest GtkD. I get a slew of unsatisfied references, all of which 
seem to feature

'_D3gtk6Widget6Widget10__mixin469.....'
I just built gtkd 2.4.2, and am linking against a libgtkd-2.a in 
/usr/local/lib with today's date.

Any ideas?
