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
