Comment (by ryandesign):

 All ports using the github portgroup should specify `github.tarball_from`.
 Not doing so deprecated and I will modify the github portgroup to print a
 warning for this soon.

 I infer from the fact that the URL contains "legacy.tar.gz" that GitHub
 considers this method old and I suppose they could deprecate and remove it
 eventually so it would be wise to remove our dependence on it. Its
 replacement, the "archive" URLs, have been available for many years.
 "Archive" URLs have the added advantage that you don't get checksum
 mismatches if the project is transferred to a different owner account,
 which turns out happens rather frequently.

 For any ports hosted at GitHub where the project offers manually-prepared
 tarballs, those should be used by specifying `github.tarball_from
 releases` in the Portfile. This is not something the R or github
 portgroups could automate for you since it is specific to each project
 whether or not they offer this.

 How about modifying the R portgroup to set `github.tarball_from archive`
 when it is using GitHub, and for any existing R port using GitHub, add the
 line `github.tarball_from tarball` to them so they continue to work. When
 each of those ports is updated next, that line can be removed to switch it
 to the new download URL.
