Hi Dr. Neyaz,
We have now made the installation process on Linux/Mac much simpler.
The new instructions are located at
http://brainsuite.org/bss/bss-download/
Essentially you just have to download the install.sh script and run it as:
bash install.sh <full path to the bss installation directory>
The above problem will have been fixed in this version.
Thanks,
Shantanu
