I think the error msg is just a red herring... This is the msg I get when running autoupdate:- + autoupdate autom4te.: no such file or directory: /dev/null autoupdate.: cannot close autom4te --language=autoconf --include=/usr/local/test/share/autoconf --trace AU_DEFUN:'AU:$f:$1' --trace define:'AC:$f:$1' --melt /dev/null |: at /usr/local/test/bin/autoupdate. line 185 And here's the relevant function:- # HANDLE_AUTOCONF_MACROS () # ------------------------- # @M4_BUILTINS -- M4 builtins and a useful comment. sub handle_autoconf_macros () { my $macros = new Autom4te::XFile ("$autoconf" .
