py27-pygrib @2.0.4: error: implicit declaration of function 'g2_unpack1' is invalid in C99

Hi,

Here is my configuration : Mac OS 11.1 (Big Sur) - Xcode 12.3 - Macports 2.6.4

I'm trying to install py27-pygrib but I got an issue during the build step :

py27-pygrib install log file

The first error in the log:

:info:build g2clib.c:1802:18: error: implicit declaration of function 'g2_unpack1' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
:info:build   __pyx_v_ierr = g2_unpack1(__pyx_v_cgrib, (&__pyx_v_iofst), (&__pyx_v_ids), (&__pyx_v_idslen));
:info:build                  ^

So this is the well-known implicit function problem with Xcode 12 and later that will need to be fixed in the usual way. (Declare a function before you use it.)
