--- Comment #8 from Eli Barzilay eli@barzilay.org --- One obvious issue with the build that I see at
http://kojipkgs.fedoraproject.org//work/tasks/5865/4225865/build.log
is that Racket uses its own copy of libffi -- my guess is that there's a missing dependency that would get libffi installed, which should make Racket's build use it instead of its own.
Also, JFYI, we are going to do a new release soon, so if anyone is working on it then it would be nice to start from that. (It's going to be a major release, probably going to v5.3.)
