How to create a metapackage with one older package?

[Michael O'Brien]

	I need to create a metapackage for a port, where one of the dependency packages included in the metapackage is a revision older than current (*).  How can I get the metapackage to include an older package?

	Specifically the current ipython is version 0.11; I need to include the version of the ipython port that has ipython 0.9.1 in it, but everything else current.  This is to solve the problem that the current ipython doesn't work with the current spyder.

	Thanks!
