Created a FreeBSD port for Sagittarius Scheme for fun1, and have this:
SHA256 (sagittarius-scheme-0.5.5.tar.xz) = 1ddf2841af2d79ddf2a54346e97fe7c0e45b9c486df69b866d60e2e6c89f7e03
The only issue pending is, fixing building on 10-CURRENT, and 11-CURRENT (i386) platforms, which I need some time to look.
[UPDATE: There you go]
