Hello,

I'm attempting to make a custom top level so that I can interface with
some c functions.  I can get it to work, but I get all kinds of errors
when I try to load in the required libraries.

here are the commands I'm attempting to create it with:
linear_algebra.c contains c functions interfaced to from ocaml,
funs.ml contains their ocaml declarations.


         gcc -c -I/usr/lib64/ocaml/ -I/usr/local/cuda/include/ linear_algebra.c
         ocamlfind ocamlc -custom -c -package bigarray,lacaml funs.ml
         ocamlfind ocamlmktop -custom -o cudatop -package
bigarray,lacaml -linkpkg linear_algebra.o funs.cmo -cc nvcc -ccopt
-lcublas


This works, and I have an executable I can run to get a ocaml prompt,
however, If I try to use the libraries I linked to create the top,
I get an unbound module error.  So actually loading them with the
#load directive, or more usefully topfind, seems to "work" but
the following errors are produced.  Information on what is going wrong
and what to do is very helpful.
