LWP 5.803 build failure on Mac OS X 10.3.9

I'm trying to do CPANish things on my Panther system.  Using the "cpan"
command to install things, inevitably leads to a download of LWP, but
the test phase fails:

  html/form.............NOK 99# Test 99 got: '' (html/form.t at line 476)

  #    Expected: 'zero'
  #  html/form.t line 476 is: ok(join(":",
  $f->find_input("r0")->value_names), "zero");
  html/form.............FAILED test 99

          Failed 1/103 tests, 99.03% okay

Are there any workarounds?

Thanks,
