+If you have an error message similar to
+\verbatim
+./<project>_simulator: error while loading shared libraries: libsimgrid.so.2: cannot open shared object file: No such file or directory
+\endverbatim
+it simply means that the dynamic linker of you system fails to find
+the simgrid library. The easiest way to solve this is to declare a
+LD_LIBRARY_PATH shell variable pointing to the directory where your
+library lives (that's /opt/simgrid/lib on my machine because I passed
+--prefix=/opt/simgrid to the configure script).
