Ports with invalid dependencies

[M.E. O'Neill]

In the course of plotting the MacPorts dependency graph for my own edification, I discovered that there are some ports that have incorrect dependencies (i.e., they depend on ports that don't exist).  For the most part, these appear to be typos or name changes that were not updated everywhere.

The errors I discovered were:

	biblatex-biber -> piblatex-module-build
	p5-list-uniq -> p5.12-list-uniq
	pemail -> p5.12--mail-pop3client
	pemail -> p5.12--mime-lite
	pemail -> p5.12--term-readkey
	py-pyxmpp -> py-p-dnspython
	py-pyxmpp -> py-p-libxml2
	py-pyxmpp -> py-p-m2crypto
	rb19-main -> rb19-fattr
	yi -> alex
	yi -> happy

yi, for example, should be depending on hs_alex and hs_happy, and the py-p-* and p5.12--* ones should be py-* and p5.12-* respectively.  I don't know about piblatex-module-build, p5.12-list-uniq, and rb19-fattr.

This kind of consistency check is easy to do, and seems like it ought to be the kind of thing that's done automatically somewhere along the way.

    M.E.O.

P.S.  If I were good, I'd file tickets on these packages.  I have not filed any tickets on them, however.
