There is an incompatibility between the flac package from Fedora Core development tree and the flac package from fedora.us: while flac-1.1.0-3.src.rpm from Fedora Core devel tree consists of flac, flac-devel and flac-xmms the package from fedora.us splits this further by generating the flac-libs package. The Fedora Core devel tree approach is used by Freshrpms too so currently people who use Fedora.us and Freshrpms are affected. For instance I'm packaging K3b which requires flac, but if someone is using both the freshrpms and fedora.us/stable repositories this happens: yum detects that k3b needs flac, it installs it from freshrpms(it seems newer), but it detects at the same time that libFLAC.so.4 is needed which is provided by fedora's flac-libs. Of course when trying to install both packages yum fails. An workaround would be to issue "yum --exclude=flac-libs install k3b", but this is rather an ugly hack. I spoke with Matthias Saou (who maintains flac from freshrpms) and he agreed to change his package if the flac package from devel tree will be splitted into fedora-libs too. While this might be a temporary problem between Freshrpms and Fedora.us, things will get worse as soon as Fedora Core 2 will be released. I already submitted a bug on fedora.us about this issue ( https://bugzilla.fedora.us/show_bug.cgi?id=1397 ) but since nobody answered I followed Warren Togamy's advise and took the problem in here.
