OS X does not include pkg-config by default, and whatever mechanism installs it places pkg.m4 in some location among: > > /opt/local/share/aclocal/pkg.m4 > /usr/local/share/aclocal/pkg.m4 > > PKG_CHECK_MODULES isn't defined if pkg.m4 isn't in /usr/share/aclocal, so ./configure dies without augmenting aclocal's search path. > > My question: What is the proper way to augment this path?
