Hi,

the above cited text looks _perfect_ to me.  :-)

What about adding that to the kde.org online documentation and/or to
the respective Usenet postings?
(For german language this would be the "KDE-Kompilations-FAQ"
 of Thomas Schuetz in de.comp.os.unix.apps.kde,
 topic "2.6) Welche Bibliotheken und Zusatzprogramme benötigt KDE?"
 mentioning needed or usefull libs and add-on programs.)
