Trouble with wxGTK used by Audacity in FC4?

I'm running Fedora Core 4 on i386 (a dual CPU machine) and I have both
FreshRPMs and Fedora Extras repos set up for yum to use.  I installed Audacity
and let yum pick whatever packages it needed to satisfy dependencies.  When I
update, yum fails with the following:

> --> Processing Dependency: libwx_gtk2-2.4.so.0 for package: audacity
> --> Processing Dependency: libwx_gtk2-2.4.so.0(WXGTK2_2.4) for package: audacity
> --> Finished Dependency Resolution
> Error: Missing Dependency: libwx_gtk2-2.4.so.0 is needed by package audacity
> Error: Missing Dependency: libwx_gtk2-2.4.so.0(WXGTK2_2.4) is needed by package audacity

If I remove Audacity with yum, I can update and then reinstall Audacity.
If I stop using the FreshRPMs repo, I can update without removing Audacity
(hence my reason to write here).

Any suggestions on how to properly resolve this so that I can have Audacity
installed and update without incident?

Thanks.
