When I add your patch, there is still an error:

url-http.el with patch from describe function, just to make sure patch
is applied:
   ...
    (setq request
          (concat
             ;; The request
             (or url-http-method "GET") " "
             (url-http--encode-string
             ;; (if using-proxy (url-recreate-url url-http-target-url)
real-fname))
             (if (and using-proxy
                 (not (equal "https" (url-type url-http-target-url))))
                 (url-recreate-url url-http-target-url)
              real-fname))
             " HTTP/" url-http-version "\r\n"
    ...

output from make:

  ELC      url/url-http.elc

Sorry if the extra info is extraneous, just trying to grab as much as
I can for you.  I think there is something else wrong at this point
though - like I mentioned it seems strange I had to run
package-install 4 times to get excorporate to install in the first
place.

Thanks!
