The recently produced ocaml package assumes that it will be able to find "-lcurses" when it links programs. I had to download the libncurses-devel package to get the linker working. I expect this should be included among the dependencies. (Perhaps gcc should as well, since the ocaml linker expects to use gcc.)
(Before that, when I rolled my own ocaml, it always linked with -ltermcap instead. Forgive my ignorance, is it much better to use -lcurses instead?) BTW thanks for creating this package, it's something I had been intending to do myself for months now. Robert
