Please add alpha to the list of arches where HelixPlayer cannot be used. Search for sparc in the spec and add alpha to the list. There are three lines - sorry to lazy to provide a patch for that now. Maybe you better add some no_helix_arches define at the top, so you don't need to change it in 3 places every time :-)
fwiw, HelixPlayer includes only: ExcludeArch: ppc64 x86_64 s390 s390x ia64 perhaps HelixPlayer/amarok should both start using whitelists of known-working archs, instead of blacklists. So, HelixPlayer works on what? i386, ppc ? anything else?
I've got a simple specfile solution here, pending confirmation of archs.
IIRC ExclusiveArch is discouraged, so I just added alpha to the list (this should not change too frequently so I didn't use defines) I've also added alpha (and sparc and sparc64) to HelixPlayer's specfile. Thanks, it should be fixed in 1.4.7-6 (rawhide)
