Yes, but then how do you uninstall it? What if a newer official release shows up in the apt sources?
I realize its a matter of point since DOSBox isn't that messy of an install, but other programs are. We should not have to resort to sources. And if DOSBox doesn't come out with a release at least once a year, that's what we'll have to do.
Most package maintainers don't even look at CVS versions. They just package up official releases and never look back. You'll get more users of DOSBox if an up-to-date version is available via YUM or apt-get/synaptic on a frequent basis.
