It's quite simple - your mpi-enabled compiler command cannot find the
library file libnsl.a, which probably means it is not setup correctly
since the file is obviously present on your system. Either ask your
sysadm to fix it, or locate the file yourself and explicitly add that
location as a library search path by putting it in LDFLAGS.
