I have been playing with porting heimdal 1.3.2 for a couple days now; as 
far as I can tell, MD2 is not optional for heimdal. I see three options
- build openssl 1.0.0 with MD2
- build heimdal with hcrypto (it won't use openssl then)
- patch heimdal to remove MD2 support

The first is the easiest and the way I have been testing the port, but I 
might take a look at adding a knob to enable hcrypto. Removing MD2 would 
require more effort than I am willing to spend at the moment.
