     Type:  defect           |     Status:  new
 Priority:  Normal           |  Milestone:
Component:  ports            |    Version:  2.6.4
 Keywords:  bigsur arm64     |       Port:  pandoc stack
-----------------------------+--------------------------
 Invoking the command `sudo port install pandoc` fails with the following
 errors:
 {{{
 --->  Computing dependencies for pandoc
 Error: Cannot install pandoc for the arch 'arm64' because
 Error: its dependency stack only supports the arch 'x86_64'.
 Error: Follow https://guide.macports.org/#project.tickets to report a bug.
 Error: Processing of port pandoc failed
 }}}

 This seems different from the prior issue pertaining to the stack port.
