Obviously, I'm not going to accept this patch as is, since it removes
all the modifications I have made to the package.  However, I did go
ahead and update to 3.0.4, which is now working its way to mirrors.

Since this would conflict with the existing python-wx package, either
this needs to be a compatible replacement for 3.0, or the packaging
needs to be modified to be parallel-installable.
