update 1

thanks. if try install dpkg -i mpich2_1.4.1-1ubuntu1_amd64.deb first have remove previous version 3.0.4, because in conflict.

i remove it, try install 1.4.1 there unsolved dependencies (libmpich2-3 -1.4.1 not installable, libcr0 not installed, libhwloc4, hwloc-nox). suggested run apt-get -f install installs 3.0.4 on debian works fine, 64 bit, wheezy release. on ubuntu 14.04, 64 bit, doesn't work.

you asking how can downgrade vendor-packaged mpich-3.0.4 mpich2-1.4.1

debian , ubuntu make upgrading easy. downgrading little tricky , might require pinning package, rebuilding old .deb newer platform, or can build mpich2-1.4.1 source.

debian: https://packages.debian.org/wheezy/mpich2

ubuntu: http://packages.ubuntu.com/precise/mpich2

source: http://www.mpich.org/static/downloads/1.4.1/

a word of caution: if ask mpich2-1.4, first thing going hear "wow, 2 years old. can try latest version?"
