Hi Andrea,

I'm sorry, I don't really know how to make a minimal working example
that downloads and installs packages. Do you know of any examples that
I could learn from?

I'd never heard of a generalized variable, so I've read some of the
relevant sections of the Emacs manual. I can't tell whether the line
in question:

    (setf (url-port address) (url-port current-address))

should behave "correctly" (whatever that means). But elpher requires
'url-util, which in turns requires 'url-parse. So I would have
expected `url-port' to be a valid function at this point, because it's
defined in lisp/url/url-parse.el. I'm particularly confused because I
only see the warning once elpher has been compiled to native code. So
there does seem to be some difference in behaviour between the byte
code and native code, at least on my computer.

That's interesting, when I see this warning there is nothing else
displayed in the `*elpher*' buffer. It only contains the error message
and a reminder to press `u' to return to the previous page.

I've found an email address, so I'll contact the author and see if
they're able to shed any light on this.

Thanks again for your time, patience, and assistance.

All the best,
Rob
