LinuxMint 11 support and "no distro" detection

[wulftone]

added support for LinuxMint and tested install on LinuxMint 11 (gnome) also made it raise an error if no distro detected

Interesting. Does just rake work, or does the full CouchDB build work?

It's just rake that doesn't work - it fails immediately with:

detect_distro() returns nil because Linux Mint has both /etc/lsb-release and /etc/debian_version files, but /etc/lsb-release doesn't contain "Ubuntu", so none of the checks in detect_distro() match.

I can confirm that this patch fixes the error for me on Mint 12 - it would be very useful if it was merged.
