I've used a separately installed MiKTeX version together with 
Lilypond and it's never been necessary to fiddle with the
PATH variable. The file /etc/profile.d/ finds
the path to MiKTeX from the registry and adds it automatically
to the PATH variable. If you have some other TeX distribution
or a MiKTeX version where this solution doesn't work, it would
be great if you could modify and send the solution
to the list.

Again, this should not be necessary. In fact, it may cause 
problems since lilypond cannot calculate the length of text
strings from the .afm files of certain fonts that are included
in MiKTeX but not in teTeX.

Agreed! MiKTeX causes some troubles and the current tricks
to work around these are not fully satisfactory.
