So aclocal generates it for you.  If aclocal reads the files in
/home/ed/local_first/buddy/share/aclocal, then you're set.

Another possibility is for you to ship these files alongside in your
package: in that case, aclocal.m4 won't contain their contents, but
include them with m4_include statements.  For this to work, put
  AC_CONFIG_MACRO_DIR([m4])

in your configure.ac (given of course you have a m4/ directory in your
source tree), and use `aclocal --install' or `libtoolize --install'
(CVS Libtool only) to add them there.  Don't forget the
  ACLOCAL_AMFLAGS = -I m4

in the toplevel Makefile.am in this case.

Harmless, but maybe over-ambitious, and confusing for the user.
