Code review comment for lp://staging/~nejucomo/divmod.org/fix-nevow-setup

Ah, I misread the error output. It was unrelated to `nevow.test.test_url.Serialization.test_rfc1808` but instead occurred in `nevow.test.test_consolejstest.JSGenerationTestCase.test_generateTestScript`.

I'm now investigating if a js interpreter is needed, and how it is detected. I have node on my $PATH, but it was not detected...
