[Pki-users] building dogtag

I am trying to build dogtag from the latest SVN trunk using the default Fedora 8 installation. While running the build_pki script, I receive the following unmet dependencies: [exec] error: Failed build dependencies: [exec] java-devel >= 1.6.0 is needed by osutil-1.0.0-4.fc8.i386 [exec] nspr-devel >= 4.6.99 is needed by osutil-1.0.0-4.fc8.i386 [exec] nss-devel >= 3.12.0 is needed by osutil-1.0.0-4.fc8.i386 I've tried to update these rpms, but there are no updates available for Fedora 8. Should I upgrade to Federa 9 to get these packages? Thanks
