 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.6.2

------------------------+--------------------
 Today I installed macports on my new macbook pro (Catalina 10.15.5). Xcode
 11.5 Build version 11E608c

 The base install of macports and all my usual ports installed fine except
 for GMT6. The screen said:
 --->  Found 1 broken file, matching files to ports
 Error: Port gmt6 is still broken after rebuilding it more than 3 times.
 Error: Please run port -d -y rev-upgrade and use the output to report a
 bug.
 Error: rev-upgrade failed: Port gmt6 still broken after rebuilding 3 times
 Error: Follow https://guide.macports.org/#project.tickets to report a bug.

 I've attached the output of port -d -y rev-upgrade to this ticket. I would
 appreciate any help you could offer for me to get GMT6 installed. Thanks.
