I don't actually use rvm to build HEAD, since I have my llvm setup differently and because I have other changes to MacRuby; however, I do use HEAD with rvm.
The trick is that rvm sets up macruby a little differently, and that macruby-nightly and macruby-head would be installed to the same place anyways.
Steps:
1. install macruby-nightly using rvm so that rvm sets up paths, directories, symlinks, etc. that rvm wants for gemsets and like
2. build macruby HEAD without rvm and then install it
3. sacrifice a goat under the full moon
4. tell rvm to use macruby-nightly, except that it will really be symlinked to macruby-head
Note that you will need to re-install macruby-nightly through rvm each time the macruby version number gets bumped to fix the symlinks again. Also, step 3 is optional. Other than that, it should be smooth sailing.

MacRuby commands like macgem -- they pick up environment variables set

Subject: Installing MacRuby HEAD
To: rubyversionmanager@googlegroups.com
I'm new to this group (hi!). Yesterday I built MacRuby from HEAD,
outside of RVM, and it worked fine. There was a small complication in
that I have a 32-bit Mac, so I built it with rake archs=i386.
Now I'm trying to do the same from within RVM. The first complication
was that I had 'export rvm_make_flags="-j 3"' in my ~/.rvmrc. When
building MacRuby, rake picks up rvm_make_flags, which causes it to
error out because it doesn't recognize -j. So I commented that line
out of .rvmrc.
Next, I found that whatever I tried, RVM would not call rake with
archs=i386, so it was targeting x86_64. I fixed this by editing
~/.rvm/scripts/functions/manage/macruby, changing
'rvm_ruby_make="rake"' to 'rvm_ruby_make="rake jobs=3 archs=i386"'.
This seemed to build MacRuby just fine, but failed to install RubyGems
afterward. Here is the output I get from rvm install macruby-head:

I've taken all my macruby-head logs and put them at
<https://github.com/echristopherson/macruby-head>.
So, I'd like to know:
1. What I need to do to get macruby-head installed; and
2. Whether it would be possible for RVM to be modified to allow .rvmrc
to specify build settings separately for different implementations, so
that e.g. it doesn't try to pass rvm_make_flags to rake as if it's
make. It doesn't seem right to have to modify .rvmrc each time you
compile something.
