Comment (by ryandesign):

 I see you [https://github.com/macports/macports-ports/pull/5243/files
 proposed an update to 1.63] a couple months ago but closed it because the
 distfile was not on maven. (So how did you successfully build it on your
 system prior to submitting the pull request?) Is there a reason why we
 can't get the file from [https://www.bouncycastle.org/latest_releases.html
 the project's web site] or [https://polydistortion.net/bc/index.html its
 mirror]?
