Building OpenPanel from source
From Openpanel Documentation Wiki
1.0 note: wharf is unsupported and has not been updated for a while.
For Debian/Ubuntu-users: dpkg-buildpackage -rfakeroot should work in most hg checkouts (we suggest updating debian/changelog to set the versionnumber to something suitable). For CentOS/RedHat/Fedora-users: all of the 1.0 software is untested for your distributions.
