It works for me in pbuilder if I set OMPI_MCA_orte_rsh_agent=/bin/false:

It looks like orte_init failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during orte_init; some of which are due to configuration or
environment problems. This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):
orte_plm_base_select failed
--> Returned value Not found (-13) instead of ORTE_SUCCESS
