Binary installation is a little more tricky. Percival must be installed in the /usr/local/percival. It expects to find perl and all supporting packages in /usr/local/avalon. Other configurations are not supported at the moment. It is possible to relocate Percival and its supporting packages but you should be prepared to write some scripts.
First, you have to download following tarballs:
gunzip -c Percival-Perl.tar.gz | tar -xvf -
gunzip -c Percival-Apache.tar.gz | tar -xvf -
gunzip -c Percival-RRD.tar.gz | tar -xvf -
gunzip -c Percival-Source.tar.gz | tar -xvf -
