I built a fresh/up-to-date Sol 10 Update 6 x86 disk.
I installed the Sun Studio 12 compiler.
I still can not get the mdb dmod file to load.
We downloaded and installed this Sun compiler.
I still get errors...

William,
I found it:
http://bugs.opensolaris.org/bugdatabase/view_bug.do;jsessionid=a68c8de18
7c30929fb79755edd017?bug_id=5102797
So you probably will have to download mdb code and build whole kmdb with
your extension ...
-Dmitry.
