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?
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.
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
