hi! i was trying to build mpich2 with empi and the build fails just after "configuration done" with /var/tmp/portage/mpi-mpich2/mpich2-1.0.8/temp/environment: line 3438: --with-pm=mpd:gforker: command not found (content of the script) 3439: econf $(mpi_econf_args) ${c} ${romio_conf} --docdir=$(mpi_root)/usr/share/doc/${PF}; 3438: --with-pm=mpd:gforker --disable-mpe $(use_enable romio) $(use_enable !nocxx cxx) || die; how is it possible to fix this? thanks Vittorio
