Hardcoding program names like this isn't really going to work well as a
general solution.

I was going to suggest you could just configure for your system with:

  ./configure PERL='/usr/bin/env perl'

and it will substitute that into the scripts for you, but the configure
script in Automake 1.17 exits with a fatal error if it determines that
$PERL contains spaces.  We should probably make this non fatal since the
check is clearly too broad.  You can patch configure to not exit:

--- configure~
+++ configure
@@ -3514,7 +3514,7 @@ case $PERL in
    as_fn_error $? "perl not found" "$LINENO" 5
    ;;
  *' '* | *'	'*)
-  as_fn_error $? "The path to your Perl contains spaces or tabs.
+:  as_fn_error $? "The path to your Perl contains spaces or tabs.
 This would cause build failures later or unusable programs.
 Please use a path without spaces and try again." "$LINENO" 5
   ;;

and then it will let you set PERL='/usr/bin/env perl' and it will work.

Hope that helps,
  Nick
