I'm no expert, but which/whereis have always bitten me in painful ways
when I used them in my .profile/startup scripts. You can't rely on the
platform from giving you something consistent. But, something simple in
Makefile.PL could work and be reliable. Like this:

sub which {
    my $prog = shift;
    for (split(/:/,$ENV{'PATH'})) {
        my $fullpath = "$_/$prog";
        return $fullpath if -x $fullpath and -f $fullpath;
    }
    return undef;
}

(Although this code is broken if $PATH contains a double colon or ends
with a colon.)
