thanks for the fast reply
libxml2-2.2.66.tar.gz should be installed now ?! (configure, make, make-install worked without probs)
Nevertheless kino gives the error message (look above at post no. 1, please).
The file xml2-config evidently exists!!! It is in the folders
(although the links are done automatically when compiling I did it manually again --cflags and this stuff (written in the libxml2 faq))
