hi karen,
i see you are trying a development version of the mesasdk.
try recompiling r10398 with the current release version
http://www.astro.wisc.edu/~townsend/resource/download/mesasdk/mesasdk-x86_64-linux-20180822.tar.gz
for the record, i’m unable to reproduce this error
although i am using a different architecture.
