Ok, an example:

| $ cat foo.spec
| ...
| %if 0%{?_with_foo:1}
| BuildRequires: foo-devel
| %else
| BuildRequires: bar-devel
| %endif
| ...
|
| $ rpmbuild -bs foo.spec --with foo
| --> foo-*.src.rpm
|
| $ rpm -qR foo
| foo-devel

'apt-get build-dep foo-*.src.rpm' will now try to install 'foo-devel',
but 'rpmbuild --rebuild foo-*.src.rpm' will need 'bar-devel'.

Simple rpm-header examination of the src.rpm is not sufficient (or
better: is wrong) for build-dep calculation.

(things get really strange when you have something like

| %define _with_foo  %(test -e /usr/lib/foo && echo 1 || echo 0)

which will be built in a chroot environment)
