aclocal not looking into /usr/local/

[Hans Aberg]

[I am not on this list, so please cc me.]

On Mac OS X 10.6.6, I have:
 $ /usr/bin/autoconf --version
 autoconf (GNU Autoconf) 2.61
This comes with the system.

 $ /usr/local/bin/autoconf --version
 autoconf (GNU Autoconf) 2.68 
The latter was installed by ./configure && make.

When running the ./autogen.sh script on Guile from GIT, which calls
  autoreconf -i --force --verbose
aclocal does not look into /usr/local/. I have to rename /usr/share/aclocal and 
replace it by a soft link to /usr/local/share/aclocal.

In addition, adding to autoreconf the argument -B /usr/local/share/aclocal, it 
is not passed on to aclocal.
