The vim/gvim package makedepends and depends on 'libffi', but there is no reason to. Nothing in vim uses libffi, it isn't linked to it and it isn't even invoked via a dlopen() interface.

The only mention of libffi in the code is in configure.ac: https://github.com/vim/vim/blob/f49e5640821d8ef752fb50d99edcf40bb62a4d4d/src/configure.ac#L989

It's guarded by --enable-mzschemeinterp which we don't enable (depends on racket) and all it does is add -lffi to the $MZSCHEME_LIBS, even though racket itself depends on and links to libffi as it should. It's quite unclear why vim needed to add this indirect and unused dependency in https://github.com/vim/vim/commit/9e902190328f5d90305828f10fd0806fc07477e2, but the answer will probably end up being "Ubuntu's racket install is broken"?
