FAH provides a V7 client installer for Debian / Mint / Ubuntu / RedHat / CentOS / Fedora. Installation on other distros may or may not be easy but if you can offer help to others, they would appreciate it.
Mint is a distro listed in the installation Guide and is listed under the Downloads for the software under Debian, Mint and Ubuntu, so is not an unsupported version of Linux. A forum search will show a number of postings on this issue, the current FAHControl depends on an older version of Python than is installed by default with the latest Mint version. There are some workarounds posted on installing the older Python version.

You's think that a later version of Python would work, but the python development team has not been particulary supportive of such releases. Moreover, those who create the Linux install packages only ship the latest and you have to search for the kind of .deb that Steve Willis found for you. (I've see the same problem on other distros)
