I assumed that your fonts were setup completely.  I missed that you
didn't have 'mkfontdir' there.

My suggestion is subordinate :-)  You can't do anything useful
without the 'mkfontdir'.

I think so.  I don't know how this works, either.

Looks like it.  In emacs from CVS, I think it is 'fontset-default'.
That fontset is the only one that appears to be prepared to show
tamil/telugu/kannada/... once the corresponding lng-util.el is
written.

This code parallels 'setup-fontset-default' in international/fontset.el.
These glyphsets are not listed in 'x-font-name-charset-alist' and
so aren't setup for all fontsets.
