olpcsound has been reported as having a conflict with the csound package. see https://bugzilla.redhat.com/show_bug.cgi?id=473185 Originally it was only meant to be built on OLPC targets. One of the solutions is to remove the package from the FC* targets and keep it only on OLPC*. I am opening this bug to request this, if it is found to be the correct way forward
You have to create a ticket at https://fedorahosted.org/rel-eng to get this done. The chances that someone who can help you will notice this bug report are very low, because it is assigned to you and therefore very hidden to the people with the power to help you. I therefore close this bug report.
