It's trying to access this directory because that's where mesasdk was installed when I built the SDK.  However, these references to /home/townsend/mesasdk shouldn't matter, because the SDK installs a wrapper script which overrides these library paths -- see $MESASDK_ROOT/bin/gcc.wrapper.

In any case, the problem is fundamentally that the gfortran executable (gfortran.exec) can't find the standard math library (libm.so) installed on your system. To track this library down, can you send me the output of 'ls -l /lib64'

Many thanks,

Rich
