[CentOS] Firefox3 for CentOS4 -- dependency on evolution28 packages?

I'd been putting off installing the FX3 packages because of some extensions I use that don't have upgrades. [*] However, when FX1.5 crashed on me today I decided to finally go ahead. Fired up yum and I'm told I have to install a slew of evolution28 library packages in order to install the firefox package. Why? I removed evolution from my system for a reason, and I'd just as soon it stays gone.

[*] Additional off-topic rant: Why was the API access to form history removed from Firefox? Why must I throw away my entire history to get rid of a few typographical errors to reduce the number of bogus field completion choices I'm offered?
