Mac OSX 10.15.7 
XCode 12.0

I am attemting to build  using the insttructions provided by the README.BUILD from the source distribution of GNAT.

I configure successfully from my /opt/GNAT/2021/obj directory with

../src/configure --enable-languages="c,ada" --disable-libada --with-gmp=/usr/local/Cellar/gmp/6.2.1 --with-mpfr=/usr/local/Cellar/mpfr/4.1.0 --with-mpc=/usr/local/Cellar/libmpc/1.1.0

Although My /usr/local/include directory does include  libintl.h
 make bootstrap fails with:
In file included from ../../src/libcpp/charset.c:21:
../../src/libcpp/system.h:279:10: fatal error: libintl.h: No such file or directory
 #include <libintl.h>

Assistance with solving this problem will be greatly appreciated.
