If that's the only problem, then I already fixed it about 2 hours ago.

You are wrong.  Please read the code, don't just judge it by the name
of the package (which is just a historic incident).

"C-h v ispell-program-name RET" would have shown its documentation.

"M-x customize-group RET ispell RET" would have shown you all the
customizable options for the package.

I suggest to spend some time learning to use the Emacs help commands,
such as the two commands I show above, they usually make discovery
fast and efficient.

In any case, since Emacs already looks for known spell-checkers, and
already prefers aspell, my conclusion from the fact that it didn't
work for you is that you have some unusual setup, which should be
quite rare nowadays.  The defaults are set such that the user will not
need to know about this variable.

I don't think it should be.  When you install a speller such as
aspell, if its executable file is not on PATH, your system is
misconfigured.  The Emacs manual is not the place where people should
look for information about setting up spelling on misconfigured
systems.

IOW, spelling with aspell in Emacs should work as long as invoking
aspell from the shell prompt works.  If it doesn't work to invoke
aspell from the shell prompt, then you should first correct your
system's configuration so that it does.
