I cannot import cartopy. I tried both python 3.7 and 3.8 with same result, on 2 different machines. macport just self updated + outdated packages upgraded as well. The error message is

libgeos_c.dylib is in /opt/local/lib

with the current version (0.19.0.post1) I do not see this issue and, therefore, assume it has been resolved. I am going to close this ticket; if the problem persists feel free to reopen.
