Yes. Hao (of Rmpi fame) and I also see it on 64-bit Debian and Ubuntu, but
not on the 32-bit variants. AFAIK it has something to do with how OMPI uses dlopen
and which symbols get across to different library.
You can suppress it via
$ tail -4 /etc/openmpi/openmpi-mca-params.conf
# edd 18 Dec 2008
mca_component_show_load_errors = 0
or using the equivalent switches on the command-line or via an env. var --
see the OMPI docs.
You may want to subscribe to r-sig-hpc to ask these types of questions there.
Three out of two people have difficulties with fractions.
