A friend of mine wanted the liboost libraries installed on our shared computer so after installing libboost-all-dev 1.49.0.1 ( A debian wheezy machine ), I get this error when using the "pydoc modules" command on the commandline. It spits out the following error --

root@debian:/usr/include/c++/4.7# pydoc modules

Please wait a moment while I gather a list of all available modules...

--------------------------------------------------------------------------
It looks like orte_init failed for some reason; your parallel process is
likely to abort.  There are many reasons that a parallel process can
fail during orte_init; some of which are due to configuration or
environment problems.  This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):
  orte_ess_set_name failed
  --> Returned value A system-required executable either could not be found or was not executable by this user (-127) instead of ORTE_SUCCESS

I tried looking into the problem and ended up uninstalling the following to get it to work again.

openmpi common all 1.4.5-1
libibverbs-dev amd64 1.1.6-1                                   
libopenmpi-dev amd64 1.4.5-1                                   
mpi-default-dev amd64 1.0.1
libboost-mpi-python1.49.0

although pydoc works again, I'm assuming the packages I removed are gunna hurt somethiong else down the track ? As you guessed im not a c/c++ programmer. So I guess my question is, will this hurt something later ? is their a way to install those packages without hurting python ?
