+For dynamically linked executables:
+
+* Ensure that the Darshan library is present in the list of shared libraries
+  to be used by the application, and that it appears before the MPI library:
+----
+> ldd mpi-io-test
+	linux-vdso.so.1 (0x00007ffd83925000)
+	libdarshan.so => /home/carns/working/install/lib/libdarshan.so (0x00007f0f4a7a6000)
+	libmpi.so.12 => /home/carns/working/src/spack/opt/spack/linux-ubuntu19.10-skylake/gcc-9.2.1/mpich-3.3.2-h3dybprufq7i5kt4hcyfoyihnrnbaogk/lib/libmpi.so.12 (0x00007f0f4a44f000)
+	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f0f4a241000)
+        ...
+----
+
+General:
 
 * Ensure that the linker is correctly linking in Darshan's runtime libraries:
     ** A common mistake is to explicitly link in the underlying MPI libraries (e.g., `-lmpich` or `-lmpichf90`)
