The `-x' operator WFM.  Does, say, this script fail for you (make sure perl
is *actually* executable) ?


  if (-x "/usr/bin/perl") {
    print "yupp, perl is executable.\n";
  } else {
    print "ut-oh! perl isn't executable.\n";

If you haven't already posted cygcheck[1] output, that might help, and also
post your script (I couldn't find it in my archives).  Sorry if you've
already done this.
