[bug-gsrc] Attempting to build/install gsrc undert Mac OS X El Capitan (10.11.6)

[Samuel Dupree]

I am attempting to install the GNU Source Release Collection (GSRC) 
software on a MacBook Pro running Mac OS X 10.11.6 (El Capitan). I'm 
having a problem with the GSRC software. In running the bootstrap 
command, I get the following:

users-MacBook-Pro:~ user$ cd gsrc
users-MacBook-Pro:gsrc user$ ./bootstrap
autoreconf: Entering directory `.'
autoreconf: configure.ac: not using Gettext
autoreconf: running: aclocal --force
aclocal: error: aclocal: file '/usr/local/share/aclocal/gtk-3.0.m4' does 
not exist
autoreconf: aclocal failed with exit status: 1
users-MacBook-Pro:gsrc user$

Please advise.

Sam Dupree.
