Marius,
thanks for looking into it! I took the updated Portfile and placed in my local tree, \
but got this error about @rpath/libgfortran.5.dylib missing
I have gcc10 and gcc11 installed, and compiled many fortran programs with gfortran 11 \
and they run properly. In /opt/local/lib/gcc11 I see this symbolic link
libgfortran.5.dylib -> /opt/local/lib/libgcc/libgfortran.5.dylib
but
/opt/local/lib/libgcc/libgfortran.5.dylib
is not there, and I see instead
/opt/local/lib/libgcc/libgfortran.5.dylib.mp_1632812346
so I'm not sure if something is wrong with my gcc installation. Maybe I should better \
delete and reinstall Macports, just to be sure. This is a test machine, so no risk of \
breaking anything (but I'm probably going off topic now…)
Anyway, I copy below the last part of py39-matplotlib-basemap/main.log
I've really appreciated your help!
Ciao
Franco
