Although there is a good build in koji http://koji.fedoraproject.org/koji/buildinfo?buildID=217000, there isn't any aalib package for EL6 anywhere. Maybe you forgot to push it to bodhi?
That build is expired now, but please do build and push a version for EL6. The package builds fine in mock locally.
