Rebuild Rmpi package for MPICH2

• Default debian package r-cran-rmpi is depended on lam4 not mpich/mpich2

  Source: rmpi
  Section: math
  Priority: optional
  Maintainer: Dirk Eddelbuettel <edd@debian.org>
  Build-Depends: debhelper (>> 4.1.0), cdbs, r-base-dev (>= 2.4.0), lam-runtime, lam4-dev (>= 7.1.1-3.2)
  Standards-Version: 3.7.2
  

• First, download source of rmpi package. Use apt-get build-dep to check the build dependence. Since LAN/MPI will confuse the configure of rmpi package, here we remove the related package which is installed by apt-get build-dep command.

  # apt-get source rmpi
  # apt-get build-dep rmpi
  # apt-get remove --purge lam-runtime lam4-dev
  # apt-get install autoconf automake
  # cd rmpi-0.5-3/
  ~rmpi-0.5-3# 
  

• modified configure.in
