Sorry, the algo in main seemed like it was an issue from previous versions.  I'm currently running 4.2.1-96-g77c99 now.  Was able to start and switch pools without algo statement in main. 

My suggestion now would be to download the latest version.  Since I'm using Linux, I'm able to download source and compile.  Looking at git source, another change has been made since my last download and compile yesterday.  Using PiMP 1.5.5Beta w/14.4 Catalyst on two and 13.12 on another.
