The project setting should be changed in XCode (right now they say to  
build for at least 10.4, and these settings are followed by the  
xcodebuild command called from make). Also, the Makefile.OCaml has to  
change for the cltool compilation (see around line 158).

Right now, everything is set to compile for both 10.4 and 10.5, but  
requires a specially built ocaml (which is simply a line to add in a  
configuration file in godi). The reason for this is that I don't have  
access to Tiger machines anymore and I want to provide a single binary  
for our users.

We could try to do some tweaking to allow different compilation  
options, but I would first need to find out how to change the target  
SDK from the command line (right now I only know how to do it in XCode).
