Right -- I now understand the problem.  See for example my email here:

https://www.redhat.com/archives/fedora-packaging/2008-March/msg00105.html

What I _don't_ understand is how to fix this ...  Obviously bug 235755
("rpm doesn't allow 'Requires: foo.%{ARCH}'") would be an ideal fix.
In the absence of that can someone suggest a workable scheme?

I can add file deps, I think, to solve this:

  In ocaml-pcre-devel:
    Requires: %{_libdir}/ocaml/pcre/  (get the right ocaml-pcre)
    Requires: %{_libdir}/libpcre.a    (instead of pcre-devel)

would seem to fix this, at the cost of downloading the filelists.
