If you want to build the manpage, you will need ronn. Newer versions of Debian come with a package:
apt-get install ruby-ronn
sudo make install
sudo make uninstall
There is another, more thorough, version. Just make sure you are not running this when you have installed to an important directory which is empty, otherwise.
THIS WILL DELETE /usr/local IF YOU INSTALLED THERE AND IT'S EMPTY, OTHERWISE
sudo make purge
THIS WILL DELETE /usr/local IF YOU INSTALLED THERE AND IT'S EMPTY, OTHERWISE
This is not in the default behaviour of make uninstall for obvious reasons.
To clean up the generated manpage, run
make clean
and if you are bored, I suggest
make moo
