After installing Kranc and seeing a successful install message, I went to build the ET with the standard

   simfactory/bin/sim build -j2 --thornlist manifest/einsteintoolkit.th

like I always do when changing or adding a thorn but I received a slew of errors about undefined references with MPI(See log file for details). All of this is done on a personal computer which I have attached my previously working configuration file(I think) for, along with options and thorn lists just in case.

The make.log was made with

 VERBOSE=1 simfactory/bin/sim build -j1 2>&1 | tee make.log 

as found on the support page without any changes made that might have messed with building.
