Thank you both! Encouraged by your praise of stability of the devel-release i decided just to install the 0.9.8 release and deinstall 0.8-release. And it works fine! Perhaps anyone is interested in the fact that I did not "make install". Instead I used the nice program checkinstall (http://asic-linux.com.mx/~izto/checkinstall/).
This program builds a *rpm-Package you can work with as you are used to do so with other RPMs. For me this is an additional advantage if it will be necessary to test a further devel-release in the future. have a nice day Michael
