Ok, another attempt. John Rose has rebased the patches for bsd-port, and 
I've got a build running. The above instructions are ok, except that 
RELAX_CHECKS=true was necessary for the make portion. So my modified 
sequence:

1. get a buildable bsd-port by following Stephen Bannasch's instructions 
here: 
http://confluence.concord.org/display/CCTR/Build+OpenJDK+Java+1.7.0+on+Mac+OS+X+10.5
2. somewhere else, mkdir davinci
3. cd davinci
4. ln -s ../bsd-port sources
5. hg fclone http://hg.openjdk.java.net/mlvm/mlvm patches
6. (cd patches/make; gnumake setup)
7. export RELAX_CHECKS=true
8. (cd patches/make; gnumake)

It's building now. I believe this sequence only applies the "testable" 
items, which includes only method handles right now.

I'll report back shortly.
