[Yum] way to "fake" package install in yum like apt "Fake-Provides"?

[nosp at xades.com (nosp)]

Hi,

   I've searched the archives and can't find a solution to "faking" a
package install so yum won't complain about missing dependencies.  Is
there any way to do this?  With apt I can do:

---/etc/apt/apt.conf excerpt
RPM {
...
Fake-Provides { "libxosd2 2.1"; };
...
}
---

TIA
