OpenCV Python链接器错误

我一直试图在heroku上安装opencv无济于事.我尝试使用heroku-anvil进行安装,现在尝试通过bash shell安装opencv.首先我安装了cmake,但是当我尝试makeopencv时,我不可避免地得到以下错误:

Linking CXX shared library ../../lib/cv2.so
/usr/bin/ld: /usr/local/lib/libpython2.7.a(abstract.o): relocation R_X86_64_32 against `.rodata.str1.8' can not be used when making a shared object; recompile with -fPIC
/usr/local/lib/libpython2.7.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
make[2]: *** [lib/cv2.so] Error 1
make[1]: *** [modules/python/CMakeFiles/opencv_python.dir/all] Error 2
make: *** [all] Error 2

以下是我正在使用的确切命令:

# connect to bash shell

heroku run bash
cd /tmp

# Downloading and Installing cmake:

curl -s http://www.cmake.org/files/v2.8/cmake-2.8.12.1.tar.Z > cmake.tar.gz
tar zxf cmake.tar.gz
cd cmake-2.8.12.1/
./bootstrap
make
make install

# Download and Install OpenCV

curl -s https://s3.amazonaws.com/nerdglasses/opencv/OpenCV-2.4.2.tar.bz2 > opencv.tar.gz
tar xf opencv.tar.gz
cd OpenCV-2.4.2/
../cmake-2.8.12.1/bin/cmake -DBUILD_SHARED_LIBS=NO -DCMAKE_SHARED_LINKER_FLAGS="-fPIC" -DBUILD_DOCS=OFF -DBUILD_EXAMPLES=OFF -DBUILD_TESTS=OFF -DBUILD_PERF_TESTS=OFF -DWITH_OPENEXR=OFF -DCMAKE_FIND_ROOT_PATH=/app/.heroku -DCMAKE_INSTALL_PREFIX=/app/.heroku .
make # ERROR HERE

有人知道怎么修这个东西吗？或者,如果有更好的方法在heroku上为python Web应用程序安装opencv？
