Lintian will complain "virtual-package-depends-without-real-package-depends",
and the maintainer then fixes it.  This is supposed to be helpful to
the autobuilders, but I anticipate that its also used by dselect and
friends.  If you install X which depends on apache|httpd, then it will
bring up a conflict resolution list with apache selected by default.

If you already have a package with Provides: httpd, then you don't
get that screen (for that reason).
