Tupone Alfredo's fixes:

1) findtool does look per tool in PATH and think ./perl is the perl
executable, while is just a local directory (I have . in the PATH)

2) I got several warning for head -1 deprecated in favour of head -n 1

3) ares directory is missing some file (missing is missing :-) ) because
automake and friends is not run.

(Let's hope number 2 doesn't break somewhere "out there", if so we can always
search/replace that back.)
