llvm dev - Dec 2007 - [LLVMdev] build failure: ocamlopt: unknown option `-g'

I am at revision 45341, and I am getting a build failure on Leopard  
involving an unknown option to the ocaml compiler:

llvm[3]: Compiling optimized llvm.ml for Debug build
/opt/fink/bin/ocamlopt: unknown option `-g'.
Usage: ocamlopt <options> <files>
...


My ocaml binaries are compiled from source using fink:

(kremenek at tedbook:llvm)$ which ocamlopt
/opt/fink/bin/ocamlopt
(kremenek at tedbook:llvm)$ ocamlopt -version
3.09.3

Ah, -g to ocamlopt this looks like a new flag for 3.10. I usually  
cross-check with 3.06 on a spare machine, but minitowers don't travel  
so well. :) Fixed here:

Thanks so much Gordon!  The build works now.

If adding the -g flag is useful, perhaps we should investigate (in the  
future) adding some autoconf magic to the configure script to add -g  
when the ocaml compiler supports to it.  Currently my autoconf foo is  
pretty minimal, but I wouldn't mind looking into adding such support  
myself in the future if there is a need.
