[PATCH] Eliminate circular dependency between altrmi and phoenix

Altrmi now has code for blocks, which introduces dependencies on 
cornerstone and phoenix.  Cornerstone has code which depends on altrmi, 
phoenix indirectly has a similar compilation dependency.

What I would like to be able to do is to compile the "core" of altrmi 
first - i.e., everything except the blocks.  If that is successful, then 
compilation can proceed to phoenix and cornerstone.  If each of these is 
successful, then an attempt will be made to go back and compile the 
altrmi blocks with the latest phoenix and cornerstone class definitions.
