apologies-- i'm not familiar with the bisect package. following the 
instructions (by mildly tweaking the _oasis file and then using ocamlbuild) 
seemed to just work for me.

if the module OUnit is unbound then it means the library isn't available on the 
path. have you run "opam install ounit" at some point?

if you have the utop top-level installed you can easily try accessing the 
bisect and ounit modules from in there to check it's installed ok:

$ utop
...
# #require "bisect";;
# #require "ounit";;
# open Bisect;;
# open OUnit;;

...shouldn't throw any errors.

you need to perform that once in your shell, not after every package install. 
(if you accept all the defaults when installing opam, i believe it will add 
appropriate lines to your shell's startup scripts -- .profile, .bashrc, 
whatever.)
