Estou tentando instalar o OpenCV dentro de um virtualenv no meu Ubuntu Server 12.04. eu encontreium fio discutindo isso mas conseguiu extrair nenhuma informação dele.

Eu tentei usarpip install pyopencv mas falhou.

error: command 'gcc' failed with exit status 1

Este erro só ocorre na segunda vez que eu corropip install. Se eu excluir o restantebuild/ pasta eu recebo esse erro.

Configuring PyOpenCV via CMake...

Error: error occurred while running CMake to configure PyOpenCV.

You may want to manually configure PyOpenCV by running cmake's tools:

    mkdir build

    cd build

    cmake-gui ..    OR    cmake ..

    cd ..

----------------------------------------
Command python setup.py egg_info failed with error code 255

Eu tenho pelo menos os seguintes pacotes apt instalados.

build-essential
uuid-dev
python-dev
python-pip
libpq-dev
cmake
libboost-dev
libcv-dev
libcvaux-dev
libboost-python-dev
libboost1.48-dev

Como posso instalar o OpenCV no meu virtualenv?
