I have this specified for my local build, but I thought by specifying 
the use ocamldep, the build system would automatically pick up on the 
dependencies within the standard library. My attempt here is more to get 
a working prototype for a larger, more scalable build system, so I was 
trying to get away from having to enter each of included libraries names 
into the OMakefiles for each project. Is this possible?

I agree it is most likely running two versions, however:

C:\ocamlmgw\bin>ocamlfind ocamldep -version
ocamldep, version 3.10.1+dev0 (2007-05-21)

C:\ocamlmgw\bin>ocamldep -version
ocamldep, version 3.10.1+dev0 (2007-05-21)

That is a bit confusing: perhaps it forwards the version check with the 
one I'd like it to use, and then uses some other one to do the  actual 
work. Regardless, I'm fairly certain it is a problem with 
ocaml-mingw-maxi's findlib port, which leaves me either trying to get 
OMake to code around it, or re-porting findlib. The former seems more 
practical.

Here are the other commands you asked about, in case you are interested:

C:\ocamlmgw\bin>ocamlfind ocamldep -verbose -modules c:\testing.ml
ocamldep: unknown option `-modules'.

C:\ocamlmgw\bin>ocamlfind ocamldep -verbose c:\testing.ml
+ ocamldep c:\testing.ml

C:\ocamlmgw\bin>ocamldep c:\testing.ml

C:\ocamlmgw\bin>ocamldep -modules c:\testing.ml
c:\testing.ml: Graphics
