Hello Siegmar, this problem is already fixed in the OMPI trunk (r27770), but currently not moved to the v1.6 branch. To make it working for the v1.6 branch, just copy the following files from the trunk to your v1.6 checkout and re-run autogen.sh: ompi/contrib/vt/vt/config/m4/acinclude.execwrap.m4 ompi/contrib/vt/vt/vtlib/vt_execwrap.c
