#62872: macOS 10.10 builder can't activate py37-mypy
--------------------------+--------------------------
 Reporter:  chrstphrchvz  |      Owner:  tobypeterson
     Type:  defect        |     Status:  assigned
 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.6.4
 Keywords:                |       Port:  py37-mypy
--------------------------+--------------------------
 The macOS 10.10 builder can't build dependents of `py37-mypy` (e.g.
 `py37-scipy`) due to an error:

 {{{
 Error: Failed to activate py37-mypy: Image error:
 /opt/local/Library/Frameworks/Python.framework/Versions/3.7/bin/dmypy
 already exists and does not belong to a registered port.
 }}}

 Example:
 https://build.macports.org/builders/ports-10.10_x86_64-builder/builds/142086/steps
 /install-dependencies/logs/stdio

 I've not investigated whether the port or a previous version of it
 erroneously leaves this file behind when deactivated, but this issue is
 not observed for other macOS versions' builders.
