OK, I see.  Easy enough to fix.  Any idea why the 'depends' field is
distinct from the 'build-depends' field?  I can't immediately think of
a situation in which they would differ.  (The extra fields I added were
exactly those given to me by a user filing a bug report.)

Right, if that is confusing, it might be better for me to rename the
copy intended for the install info.

Except that I haven't got round to checking how/whether Cabal works
with nhc98 yet....
