This forum in about gtk-gnutella, not qtella.

Anyway, it looks like qtella probably wants to use a version of a libaray that you don't have installed.

I suggest you check wether Mandrake 9 also has gtk-gnutella and try that.

Alternatively you can fetch the source code of the latest version (0.94) of gtk-gnutella from http://gtk-gnutella.sf.net and compile that yourself. But only do that if you feel up to it. At the moment there are no binary packages of the latest version available.
