No :-)   (and let's not start a gnu make vs bsd make vs. cmake vs. ant
discussion now :-) ).

Specifically, we run automake on linux systems before doing release
tarballs, so the target host doesn't even *need* automake installed -
but if you want, automake runs just fine on BSD, producing "standard
makefiles" that work fine with BSD make.

Ah, there it is :) - I think "non-GNU" make doesn't handle these in
combination with paths.

"man make" on FreeBSD says:

     The $@ and $< variables are more or less universally portable, as is the
     $(MAKE) variable.  Basic use of suffix rules (for files only in the
     current directory, not trying to chain transformations together, etc.) is
     also reasonably portable.

so

$(builddir)/openvpn.cnf: $(srcdir)/openvpn.cnf.in
        sed "s|ABSBUILDDIR|$(abs_builddir)|" < $< > $@

should work.
