>From aptitude manual ("virtual packages cannot match a dependency with a
version restriction"):

For instance, say we are attempting to resolve “Depends: exim |
mail-transport-agent”. aptitude will first attempt to install the
package exim. If exim is not available, aptitude will then attempt to
install the highest-priority package whose candidate version provides
exim. If there is no such package, aptitude will install the
highest-priority package whose candidate version provides the virtual
package mail-transport-agent. On the other hand, suppose that the
dependency is “Depends: exim (>= 2.0.0) | mail-transport-agent”, but
only version 1.0 of exim is available. In this case, aptitude will not
install exim (because the version does not match), nor will it attempt
to install packages providing exim (because virtual packages cannot
match a dependency with a version restriction). Thus, aptitude will fall
back to installing the highest-priority package whose candidate version
provides mail-transport-agent.
