Hello again and thanks for your help:

fedora and Mandriva have problems with my app:
/var/tmp/rpm-tmp.42755: line 33: qmake: command not found
But above it tells me:
installing libqt4-devel
does the libqt4-devel not include qmake?
My Mandriva-Virtualbox tells me:
# rpm -q -l libqt4-devel @ grep bin/qmake
/usr/lib/bin/qmake
and yes it is in path per default installation.
Whats wrong?
Where can I get an package list of the from the standard installation altered Xen-guests?
