Hi,
I found from looking at aclocal.in, i can put a file called "dirlist"
in /usr/share/aclocal, containing the path: /usr/local/share/aclocal.

When you compile a project from source and have libraries it needs
already installed in /usr/local, then the autogen.sh scripts they
have will not see /usr/local/share/aclocal. It is impractical to
manually do aclocal -I for these cases. The aclocal -I path should
be initialized from an environment variable, like it is for autoreconf.
