It has admittedly been several years, but I distinctly remember MIT Scheme being an utter pain in the ass to get built. I'd recommend Racket for people just getting off the ground for that reason alone.
However, there hasn't been a release since 2011. The primary maintainer (Chris Hanson) is now at Google, and seems to be busy with other things. Previously, he was at MIT and used to write most of his own research projects in Scheme, so it got a lot more maintenance attention.
Last month I built MIT Scheme on my 13 year old Toshiba Satellite (and it was the cheap one in 2001) under Wary Puppy 5.5. No problems. Because of its richer feature set, Guile was another matter and I gave up.
