Now I have added AC_SUBST_DIR(musicpath) after these lines.

But something weird happens now:

./configure: line 3594: musicpath: command not found

This doesn't affect the success of configure, but I wonder why it is
there? I looked in configure itself and lo there it was:

        musicpath
        musicpath=`(
            test "x$prefix" = xNONE && prefix="$ac_default_prefix"
            test "x$exec_prefix" = xNONE && exec_prefix="${prefix}"
            eval echo \""$musicpath"\"   
        )`

But I've added nothing but that one AC_SUBST_DIR. I am using the m4 code
verbatim from the site ou have given me. Do you know what's up?

Thanks again, please CC me again on the reply :)

Regards
Josh
