Hi Daniel,
thanks for your quick reply.

Problem is not building ECL with already installed libffi. Problem is
that ECL cannot find libffi when it compiles lisp code later, for
example when starting slime:

Maybe is a way to somehow convince NixOS to put libffi in the right
environment when running ECL, but so far I have figured it out by adding
the libffi-prefix configure option in a similar way to gmp-prefix
option. It seems like a good solution.

Great!

Thanks for the comments. You can find an updated patch attached.
