This the most common problem when someone tries to install PIL library on *nix OS. It happens because you don’t have the libraries necessary to handle this kind of format, or you may have but it is not in the right place. This libraries issues are not a python’s fault. It is caused by the system, and you need to install this libraries like SaltyCrane Blog or Jj’s blog and link to the right location, but it is explained on this articles.
Their solutions solve 90% of the cases, but I need to use PIL in my virtualenv, so I have to make a link from
/home/my_user/my_env/lib . In my case, my libjpeg is named libjpeg.so.62 and I don’t have permission (it is not recommended to rename, because it can be used by other programs). So, I created a link in my virtualenv with other name
ln -s /usr/lib/libjpeg.so.62 /home/my_user/my_env/lib/libjpeg.so. Just worked on this way.
If you installed PIL with pip, you just have to uninstall and install again. But if you used easy_install I think you have to delete manually. Google it, because I think there are 2 steps to remove easy_install’ed packages.
Let me know if I wasn’t clear enough.
