The TrollTech FTP site no longer offers the qtopia-desktop-2.2.0-1-redhat9.i386.rpm file. It appears all references to the Zaurus device and its support applications/downloads were removed by Sharp at the end of 2009. Mirrors of the file do exist, but they do not pass the Manifest checks. Manual installation from mirrors fail due to libstdc++.so.5 library error.
Ebuilds removed, as it looks like this is obsolete and won't come back.
