I recall having this error and being confused by the g-wrap build.
g-wrap builds and installs its own copy of libffi if and only if there
isn't already a libffi installed when the build starts.  So this error
can be caused by:

1. Build and install g-wrap-1.9.11.  No libffi installed yet, so
g-wrap installs it.

2. Build and install g-wrap-1.9.12.  libffi is already installed.

3. Uninstall g-wrap-1.9.11.  This uninstalls libffi too.

Could that be what is happening in your case?
