Debianにlibboost-all-devをインストールした後、Pythonエラーが発生します。

私の友人が共有コンピュータにlibboostライブラリをインストールしたかったので、libboost-all-dev 1.49.0.1（Debian wheezyコンピュータ）をインストールした後、コマンドラインで "pydocモジュール"コマンドを使用したときにこのエラーが発生しました。次のエラーが発生します -

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

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

**[debian:49065] [[INVALID],INVALID] ORTE_ERROR_LOG: A system-required executable either could not be found or was not executable by this user in file ../../../../../../orte/mca/ess/singleton/ess_singleton_module.c at line 357

--------------------------------------------------------------------------
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
--------------------------------------------------------------------------
--------------------------------------------------------------------------
It looks like MPI_INIT failed for some reason; your parallel process is
likely to abort.  There are many reasons that a parallel process can
fail during MPI_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):
  ompi_mpi_init: orte_init failed
  --> Returned "A system-required executable either could not be found or was not executable by this user" (-127) instead of "Success" (0)
--------------------------------------------------------------------------
*** The MPI_Init() function was called before MPI_INIT was invoked.
*** This is disallowed by the MPI standard.
*** Your MPI job will now abort.
[debian:49065] Abort before MPI_INIT completed successfully; not able to guarantee that all other processes were killed!**

問題の調査を試みた後に再び機能するように、次の項目を削除しました。

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

pydocが再び動作しますが、削除したパッケージが他の問題を引き起こすと仮定していますか？推測できるように、私はC / C ++プログラマーではありません。だから私の質問は「これは後で傷つけますか？」です。 Pythonを壊さずにこれらのパッケージをインストールする方法はありますか？
