Let's avoid using md5 as checksum

[David Bruce]

Hi,

I'm the upstream maintainer of tuxmath, and I also want to add it to MacPorts 
and become the port maintainer for it.  So, regarding checksums, I take it 
that it would be best (from the point of view of MacPorts, and probably 
anyone else who cares to verify that they are getting unaltered source) to 
generate all three hashes and provide them at the tuxmath download site?

I'm just learning, but it seems the port process involves three things:
1. writing a working Portfile.
2. adapting the source, if needed, to get it to build properly under the port 
system.  Since I'll be both port maintainer and upstream, I don't think this 
will need to involve patches.
3. making the download site play nicely with MacPorts, which could be things 
like providing the three checksums and making it possible for ports to check 
if a new version has been released.

I submitted a trac ticket with the first draft Portfile (#14279), and it still 
seems to be in limbo.  Is there something else I'm supposed to be doing?  I 
really would like to contribute to this project.

Thanks,
