ECL common lisp has released stable version 11.1.1. It now requires libffi, which, if detected during configure, endbles it to have ffi support. In order for libffi to be detected, one needs to provide location of its headers in CFLAGS, since those are not installed on standard location. Adding cflags for local build requires adding the following functin to ebuild: pkg_setup() { append-cflags `pkg-config --cflags libffi` } It might be a better way, but I'm not aware of it. Reproducible: Always Steps to Reproduce: 1. Build ecls without setting CFLAGS to ffi location 2. :dffi is missing from *features* 3. Build ecls with setting CFLAGS to ffi location 2. :dffi is present in *features* Here's the ebuild that I use for ecl-git version. It has cflags detection feature described here: # Copyright 1999-2009 Gentoo Foundation # Distributed under the terms of the GNU General Public License v2 # $Header: $ EAPI=2 EGIT_REPO_URI="git://ecls.git.sourceforge.net/gitroot/ecls/ecl" #EGIT_REPO_URI="git://repo.or.cz/ecl.git" inherit eutils multilib git flag-o-matic DESCRIPTION="ECL is an embeddable Common Lisp implementation."
