Hi Sandra,

The LD_PRELOAD environment variable needs to point to the actual 
libdarshan.so file, rather than just the directory that contains it.

If you continue to have problems, could you also tell us what underlying 
compiler you are using (ie, gcc, icc, pgcc, etc.) and whether it is a c, 
c++, or fortran code?

thanks,
