 Keywords:               |       Port:  evolution-data-server
-------------------------+-----------------------------------
 evolution-data-server has a build dependency on python36. In the interest
 of moving this to the latest stable version, please switch to python38 if
 possible.

 Be aware that the port communicates the choice of python version to the
 build system via the patch-cmake-find-our-build-tools.diff patch; you'll
 need to update that patch when switching the python version. This is not
 obvious at first glance. If there's a way to move the specification of
 python version from a patchfile into the portfile, e.g. by specifying a
 flag to the build system, that would ensure that it's not overlooked in
 the future. If that's not possible, maybe add a comment to the portfile,
 near the python dependency, advising that the patch needs to be updated if
 the dependency is changed. The same goes for the perl and berkeleydb
 dependencies.
