I’m not sure.

However, the source of the problem is that netcdf/buildlink3.mk lacks a reference to libexecinfo/buildlink3.mk.  (It does include four other buildlink3.mk files.)  If that is added, gdal-lib builds just fine.  (I have not tried any other packages that depend on netcdf.)

Unless I hear otherwise, I’ll commit that change soonish.

This raises a broader question: when must buildlink3.mk include other buildlink3.mk files?  Are those conditions well documented anywhere?

Thanks for your help.

Cheers,
Brook
