Arch Linux

Description:

Once I try to install cffi via pip (the Python package manager), it cannot find the appropriate headers in the standard header search paths for libffi.
libffi seems to install the two header files ffi.h and ffitarget.h into an inappropriate path:

[cjurk@vm02 include]$ pacman -Ql libffi | grep '.h$'
libffi /usr/lib/libffi-3.0.13/include/ffi.h
libffi /usr/lib/libffi-3.0.13/include/ffitarget.h

They should be installed to /usr/include instead.

Additional info:
* package version(s)
libffi 3.0.13-3
* config and/or log files etc.
cffi looks for the both header files mentioned above in the standard header search paths. They cannot find it unless i manually create a symlink to /usr/include, which is a quite dirty solution to this:

gcc -pthread -fno-strict-aliasing -march=x86-64 -mtune=generic -O2 -pipe -fstack-protector --param=ssp-buffer-size=4 -DNDEBUG -march=x86-64 -mtune=generic -O2 -pipe -fstack-protector --param=ssp-buffer-size=4 -fPIC -I/usr/include/ffi -I/usr/include/libffi -I/usr/include/python2.7 -c c/_cffi_backend.c -o build/temp.linux-x86_64-2.7/c/_cffi_backend.o

c/_cffi_backend.c:14:17: fatal error: ffi.h: No such file or directory

#include <ffi.h>

^

compilation terminated.

error: command 'gcc' failed with exit status 1



Steps to reproduce:

$ sudo pip2 install cffi
