ImportError: libffi.so.7: cannot open shared object file: No such file or directory


when trying to run Guake. They upgraded to libffi.so.8, which seems to be offered in the arch repositories, but pygobject seems to have a hard dependency on libffi.so.7 judging by the error message. Either needs to require and install libffi.so.7, or detect and use later versions here.

Additional info:
* Occurs specifically when user upgrades to libffi.so.8 from libffi.so.7.
* Submitted on behalf of a bug report from a project that depends upon this https://github.com/Guake/guake/issues/1944

Steps to reproduce:
Upgrade to libffi.so.8
Try to run Guake
