[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. Hans
