Importing the cffi bits of python-twextpy results in errors like this: >>> import twext.python.sacl /usr/lib/python2.7/dist-packages/twext/python/__pycache__/_cffi_twext_python_sacl_xe128630fxbbd600c.c:2:20: fatal error: Python.h: No such file or directory compilation terminated. Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python2.7/dist-packages/twext/python/sacl.py", line 43, in <module> raise ImportError(ve) ImportError: CompileError: command 'x86_64-linux-gnu-gcc' failed with exit status 1 This is because it's attempting to build a cffi module, that wasn't bundled in the binary package (as they be). It's worth noting that there are more modern ways to use cffi that don't have this problem https://cffi.readthedocs.io/en/latest/overview.html#real-example-api-level-out-of-line All of that said, it turns out that these cffi extensions are wrapping OSX-specific libraries. So, I think the best thing to do here is to patch them out and drop the cffi dependencies. Here's a patch series to achieve that: 0001-Patch-out-OSX-only-modules-launchd-and-sacl.patch 0002-Drop-cffi-dependency-no-longer-used.patch As I started by trying to build these cffi modules at build time, I also have some other patches that may interest you: 0003-Build-with-pybuild.patch 0004-Clean-up-after-running-tests.patch 0005-Ignore-tests.patch 0006-Wrap-and-sort-control-files.patch SR
