Install:

johnrundle@Napili ~ % sudo port activate gmt6
--->  Computing dependencies for gmt6
--->  Cleaning gmt6

Then:

%python
>>> import gmt6
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'gmt6'

This port doesn't appear to intend to provide a python module. What do you expect to be able to do with it?

So here is the problem. I have been using cartopy to make nice looking maps. As of 7/31/2023, stamen.com, the company that has supplied the topography map tiles, has announced they will no longer do this, and will migrate that service to stadia.com as of 10/31/2023. However, their migration seems to be confined to web apps, not python. So matplotlib python codes that use cartopy/map tiles will no longer look as nice.

I have been looking for alternatives. For years, the standard in map making has been Generic Mapping Tools (GMT). There is a python version: ​https://www.pygmt.org/latest/ I was hoping that I could simply import this and use it. I found several Macports packages: gmt4, gmt5, gmt6. As I mentioned previously, I can install them, but when I try to import it, it does not import.

Simplest thing would be to have pygmt be a port for Macports if that can be done.

[jmroot (Joshua Root)]

OK, so gmt6 is the underlying library that pygmt would use as a dependency.

[jbrundle]

Ok. So how does one use pygmt with matplotlib on macports?

[jbrundle]

Another possibility for improving the cartopy maps is for Macports to develop a port for cartoee: ​https://pypi.org/project/cartoee/ That might be an easier way to go.
