if read through log might spot line:

c/_cffi_backend.c:13:10: fatal error: 'ffi.h' file not found 

the "fatal error" part important. :)

this means ffi headers couldn't located compiler. i'm not sure how since i'm not mac user maybe homebrew you, or google. me seems should install homebrew , run:

brew install libffi 

then try pip again.

edit

the full list of dependencies are:

• python
• libffi
• libssl
• libxml2
• libxslt1

so you'll need those, , headers, if want continue down path.

an easier solution download pre-built binaries mac, mitmproxy.org (osx mountain lion , later). found info in installation docs.
