the developer of ardour changed the download page (1) in a way that doesn't allow downloads without going through a dialogue where he asks for donation. Donation is not mandatory but there's no direct link to the source tarball available anymore. All ardour packages, including the one I maintain (2), are broken since this change.
The in my opinion best way to overcome this issue is to determine the svn revision of the release, check it out and build that instead. Although it technically using svn it wouldn't follow a branch. Would it ok to just leave the package name as is?
The other method I can think of that wouldn't need svn would be to upload the tarball elsewhere, something I rather not do.
Best regards, Philipp
