+I could build everything with the last svn revision ... only need a
+patch for LinuxSampler
+The  spec files and patches can be found in bugzilla
+bug 7575, bug 7576, bug 7579, bug 7580, bug 7581, bug 7639.
+If you want to try :
+you need to build and install the rpms in this order :
+gig
+liblscp
+lv2
+linuxsampler
+gigedit
+qsampler
+
+NB
+I don't use a buildsystem...
+I have several devel packages installed =>
+Maybe some BuildRequires are missing in the spec files
