They exist and both are actually links to the same binary
'opal_wrapper':

user_at_host:~/boost/boost_1_43_0$ file
/software/all/openmpi/1.4.2/bin/mpic++
/software/all/openmpi/1.4.2/bin/mpic++: symbolic link to `opal_wrapper'

user_at_host:~/boost/boost_1_43_0$ file
/software/all/openmpi/1.4.2/bin/mpiCC
/software/all/openmpi/1.4.2/bin/mpiCC: symbolic link to `opal_wrapper'

user_at_host:~/boost/boost_1_43_0$ file

I just tested and it can also produce executables so than it is the
right binary. I suppose that the autoconfiguration in bjam expects
something from openmpi but I have no idea what is expected. I tried the
instructions in 

http://www.boost.org/doc/libs/1_43_0/doc/html/mpi/getting_started.html#m
pi.config

"--debug-configuration" says nothing more about MPI. I also want to try
but unfortunately do not understand the hint for 
user-config.jam:

using mpi : : <find-shared-library>lammpio <find-shared-library>lammpi++
              <find-shared-library>mpi <find-shared-library>lam 
              <find-shared-library>dl ;

Best,
Ivan
