Why doesn't "rpm -q --whatrequires dbus-sharp" find the same
dependency that yum does?  This is an up-to-date FC5.i386 system.

The dependency that yum is catching isn't on dbus-sharp, but on
mono(dbus-sharp).

    $ rpm -q --whatrequires 'mono(dbus-sharp)'
    tomboy-0.3.5-3
    f-spot-0.1.10-1


Naming a package "foo(bar)" seems pretty odd to me. This is the first time I've run across it.

The package isn't *named* that, it *provides* that. A package can *provide* much more than just its name, and rpm uses those provides for dependencies just like it does with package names.

Well, at this point it's little more than an exercise in curiosity, but here's more dbus-sharp fun...

[root@petrel ~]# rpm -q --whatrequires dbus-sharp
no package requires dbus-sharp
[root@petrel ~]# rpm -q 'mono(dbus-sharp)'
package mono(dbus-sharp) is not installed

Try instead:
$ rpm -q --whatprovides 'mono(dbus-sharp)'

[root@petrel ~]# rpm -q --whatrequires 'mono(dbus-sharp)'
tomboy-0.3.5-3
[root@petrel ~]# rpm -q tomboy
tomboy-0.3.5-3
