I just wanted to let you know that on Ubuntu 14.04 at some point of the installation of the fairsoft packages I got more or less the error message that in rootconfig.sh (line 44) there are too many arugments for [.
I guess the files the message is refering to are
Lines 44 and beyond look like this:
if [ $gcc_major_version -eq 3 -a $gcc_minor_version -eq 3 -a $gcc_sub_version -eq 5 ];
The installation seemed to have worked despite of the error message.
