Well, I think I've figured it why it has failed even after installation of 'libutempter0', the profitable coin according to MPH is XMR and with the XMR the path provided in the 'mph_config.json' is invalid.
/home/m1/KTccminer-cryptonight/ccminer -a cryptonight
The miner previously accepted the -a option, but ignored it as it only has Cryptonight code in it. I pulled the latest version about a half-hour ago, rebuilt it, and found that the -a option now throws an error. Getting rid of the "-a cryptonight" part of the base command should be a sufficient fix.
