Comment 4 for bug 879944

We don't provide RPMs unfortunately, only debian packages are supported currently. You may want to try building Onboard from source though. You can get the source with

bzr branch lp:onboard

To be able to build and run it, you'd need to install a couple of dependencies. Here is the list of required (debian) packages from debian/rules, Mandrive should have those, but you may find them under different names:

python (>= 2.6.6-3~),
python-distutils-extra (>= 2.10),
python-all-dev,
libgtk-3-dev,
libxi-dev,
libxtst-dev

python-cairo,
python-dbus,
python-virtkey (>= 0.60.0),
gir1.2-gtk-3.0,
gir1.2-pango-1.0 (>= 1.29.3),
gir1.2-glib-2.0,
gir1.2-gdkpixbuf-2.0,
libgtk-3-0,
libxi6,
libxtst6

Once you have that, cd into the source directory
$ cd onboard

then build and install onboard with
$ sudo python setup.py install --prefix=/usr
(replace sudo with your preferred method to become root)

finally Onboard's gsettings schema needs to be compiled with
$ sudo glib-compile-schemas /usr/share/glib-2.0/schemas

Then you should be able to run it with 'onboard'.
