This solution is also fine with me. In the mean time, I still believe
reverting the patch that bumps to v6 is for the moment the best action
to take, until someone steps up to make the change to berkeleydb v6.

However, AGPLv3+ (the new license of berkeleydb) is a fairly strong
license, so I'm quite sure a number of embedded system markers would be
interested in having the ability to build Python, or Perl, against a
non-strongly-copyleft licensed version of berkeleydb.

But aren't all Perl modules licensed under the Artistic license? Not
sure if it can cause some problems with berkeleydb being AGPLv3+,
though.

Well, licensing information is tricky to get right. I believe the kind
of review you made is typically what makes the licensing information
progressively better.

Best regards,
