为了让我在Heroku上获得PIL JPEG支持，我必须使用这里找到的PIL的分叉/编辑版本hg + https://bitbucket.org/etienned/pil-2009-raclette/#egg=PIL
它告诉我JPEG support available Heroku但是在我当地的Ubuntu 12.04上我得到了*** JPEG support not available。
我在ubuntu机器上错过了某些软件包吗？这是使用pip和requirements.txt安装的转储
的Heroku ：

尝试执行sudo apt-get install libjpeg libjpeg-dev libfreetype6 libfreetype6-dev zlib1g-dev，然后对这些库进行符号链接：
ln -s /usr/lib/`uname -i`-linux-gnu/libjpeg.so /usr/lib
ln -s /usr/lib/`uname -i`-linux-gnu/libfreetype.so /usr/lib
ln -s /usr/lib/`uname -i`-linux-gnu/libz.so /usr/lib
并重新运行pip install，如this post中所述。
