I have upgraded to CGI.pm 3.25.  Same thing.
Here's the code in modules/http/http_protocol.c:

    switch (status) {
    case HTTP_MOVED_PERMANENTLY:
    case HTTP_MOVED_TEMPORARILY:
    case HTTP_TEMPORARY_REDIRECT:
        return(apr_pstrcat(p,
                           "<p>The document has moved <a href=\"",
                           ap_escape_html(r->pool, location),
                           "\">here</a>.</p>\n",
                           NULL));
    case HTTP_SEE_OTHER:

I've reinstalled 2.0.55 and redirects are working properly.
Perhaps the above is broken in 2.0.55.  I mucked with it a
bit and didn't get anywhere (no surprise).  Thanks for all
suggestions.  I'll take a look at CAP::Redirect.

Thanks,
Jon

P.S.  I wonder if #5 above could be a problem? (Doubt it)
