I really would expect only ImageMagick-devel to show up which has:

ImageMagick = 6.7.0.10-3.fc16

as a requires.

Version-Release number of selected component (if applicable):
yum-utils-1.1.31-2.fc16.noarch
Comment 1 James Antill 2011-11-16 15:49:59 UTC 
 This is maybe bad documentation wording (feel free to suggest changes), what is happening is that you specify:

'ImageMagick = 6.7.0.10-3.fc16'

...this is then turned into a package ImageMagick-6.7.0.10-3.fc16, and by default it looks at all the files and provides (repoquery --provides ImageMagick-6.7.0.10-3.fc16) to see if anything requires any of those things (Eg. Requires: libMagickCore.so.4).
 With --exactdeps it only looks for things which require the package name itself (Eg. Requires: ImageMagick ... or Requires: ImageMagick >= 6.7.0.10).

 You could use repoquery --tree-requires and grep to find things that match an explicit requirement exactly ... can't think of a better way. Why do you want to do that?
Comment 2 Orion Poplawski 2011-11-16 20:45:18 UTC 
In this case, things that use ImageMagick generally depend on a specific version, so they have requires like:

ImageMagick = 6.7.0.10

I wanted to verify that nothing depended explicitly on the release version as well.  Not a big deal, but I do think it would be useful to search for the explicit requires as above.
Comment 3 James Antill 2011-11-16 22:08:19 UTC 
 There is no real API to do that, and people really wouldn't want a straight text match IMO ... so it'd be "interesting" in a few cases. One workaround you can 
do is:

% repoquery --whatrequires --output=ascii-tree --level=1 ImageMagick
