An update which may add a bit more detail. 

Today I added more packages to the repository that contains what is
required by the planetccrma-apps meta package. 

I erased the planetccrma-apps package:

  > rpm -e planetccrma-apps

Then I reinstalled it (it is the same package as before with the same
requirements - the only change is that I added more packages to the
repository so that more, but not _all_, requirements are met). 

  > yum install planetccrma-apps

It happily went ahead and added the new packages but again ignored the
missing ones. Looks like a pattern of behavior[*]. After installing
successfully the meta package again, the machine is left with unmet
dependencies. 

Again, if I now erase planetccrma-apps and try reinstalling it, it fails
as it should have the first time. 

Puzzling but completely repeatable. Is there anything I could do to help
debug this? Looks like a pretty severe bug.

[*] at this point my guess is:

package with explicit named package dependencies (non-versioned). No
other dependencies. 

if we try to install and some deps are available then it goes ahead and
installs them ignoring any missing deps. 

if we try to install and all missing deps are missing then it complains
with an error as it should.
