Thanks for your help.  Installing Bin-prot has seemed to fix that error.  
Unfortunately, now I get a different one.  To give some context, I am trying 
to create an equivalent toplevel init.ml file that corresponds to the 
ocamlbuild _tags file. 

To build a project with Batteries all you need is "<*>: use_batteries" in the 
_tags file.  I don't really use ocamlbuild so I am assuming the _tags file 
plays a similar role to your normal Makefile.

My equivalent init.ml file which aims to start an ocamltoplevel in an 
environment where any code that compiles will run in the toplevel consists, 
so far of:

  #use "topfind"
  #require "batteries"

The new error is: Reference to undefined global `Ref'

I am not familiar with Ref.  It looks like it's a module in Batteries, so I'm 
not sure why it's throwing this error.  I tried to open Data.Mutable to see 
if perhaps things worked despite the warning, but it does not appear to be 
so.

Any ideas?  I've attached the complete output below for reference.


Thanks in advance,


Peng
