but there isn't in others libs. So this is the problem, isn't true?

    Looks like it, yes.  Maybe your MPI library is the wrong version (too old)? A quick grep through the current Open MPI sources shows the symbol is defined in ./ompi/datatype/dt_module.c.  But I'm no Open MPI expert, and can't tell from the top of my head if that symbol should end up in the lib (which you seem to have), or in some other related lib...

    You could try compiling the sources yourself (unless you've already done so), and check every .so/.a file being created for the occurrence of the symbol.

      Ok, I think my lib is too old. It is a package (prebuild in my distribution).
      Now I am recompiling OpenMPI lib from source.

      Thank you,
