Hi Alfons,

> Did you switch to another version of g++ lately?

...not consciously :-)

Perhaps the pkgconfig produces this problems. I installed the versin 0.15 from 
source. Yesterday I recognized that there is a "child-"directory called 
"glib-1.2.8" under the pkgconfig-0.15

How can I get rid of this pkgconfig installation or find out exactly what is 
not  matching there ?

thanks ..GERD..
===========================================
once again the error message:

1.) I'm sure having qt with thread support
    (file /opt/qt3.3.3/lib/libqt-mt exitsts, also .3/.3.3/.3.3.3)
2.) QTDIR is exported and points to the right location
   ($QTDIR=/opt/qt3.3.3)
Please remind: before installing pkgconfig I passed the section of "checking 
for Qt"

A look in the config.log (of the arts-lib) tells me:
