BTW, for each sub-package you can specify its own BuildRequires. This
works with RPM 4.x at least. This is primarily for cases when sub-package
building is wrapped by '--with-foo/--without-foo' options available in RPM
(see documentation for more). So you may put BuildRequires more fine
tuned.

Also, RH has a package named rpm-redhatdb or something like this. It
contains additional RPM database with all RH packages installed (only
database records are there of course). You can use it for resolving
dependencies against whole distribution.

Also, take a look at rpm-utils from our ALT Linux distribution. It has a number 
of utilites to ease management of BuildRequires. In particular, buildreqs utility
calculates all build dependencies needed for a package during build in a
larger installation than is really needed for build (kind of automagical
finding of 'minimal' subset of BuildRequires).

Unfortunately, you can't use it as is for RH because package naming scheme
is slightly different as well as RPM macros but it surely will reduce your
amount of work because you'll end up repeating much of its functionality
by hands (or self-written scripts).

You can find a mirror with it using RPM PBone: http://rpm.pbone.net/,
query string is 'rpm-utils*alt'.
One URI will be
http://rpm.pbone.net/index.php3?stat=4&idpl=284400&idpa=284400 (take a
source package).

Just start with default options set as in Samba Team's sample spec file.
