PG 11 when run make: 'stdio.h' file not found

Hello,

On Mac after updating my Postgres 10 to 11 with brew I'm having trouble with wal2json. I cannot make it work again. Using previously compiled version I'm getting error

ERROR: could not load library "/usr/local/lib/postgresql/wal2json.so": dlopen(/usr/local/lib/postgresql/wal2json.so, 10): Symbol not found: _AllocSetContextCreate
  Referenced from: /usr/local/lib/postgresql/wal2json.so
  Expected in: /usr/local/opt/postgresql/bin/postgres
 in /usr/local/lib/postgresql/wal2json.so

And when I'm trying to compile a new one there is another error:

I'm not sure what to do so any suggestions would be much appreciated!

Thanks.
