Compiling OpenMPI with Intel compilers can be a bit of a nuisance, and so the following seems to work with version 11.074 Intel Compilers, OpenMPI v 2.8.1 and Ubuntu 8.10:
1) Install The Intel Compilers with defaults
2) Put iccvars.sh and ifortvars.sh into /etc/profile.d, and comment out the lines referring to non 64 bit binaries
3) source /etc/profile
4) Unpack the OpenMPI
5) Run ./configure --with-fortran CXX=icc FC=ifort LIBS=-lstdc++
6) type LANG=C
7) make all
8) sudo make all install
9) sudo ldconfig
10) type mpiCC --showme to verify the compiler wrappers are working correctly
