If it can be of any help: here at Middlesex University we managed to compile the standard sources for 5.93 on a Raspberry Pi (standard raspbian distro). The only thing we had to do was to disable documentation in the configuration step (configure --disable-docs). And then wait a few hours.
Regarding serial communication: we are currently driving an Arduino Uno board connected via serial port to the Raspberry Pi from Racket using a modified version of Firmata. This version is available here: https://bitbucket.org/fraimondi/racket-firmata The Arduino Uno is then connected to a pair of wheels and to bump and IR sensors. A full description of the robotic platform is here: http://www.rmnd.net/middlesex-robotic-platformo-mirto/ I cannot comment on stability over a long period of time, but Racket performs quite well to read / write to the serial port and control wheels and sensors to follow a line is a smooth way, implementing a 100% Racket-based PID controller (25 Hz): http://www.youtube.com/watch?v=laafaTZ7mDU&t=4m46s Raspbian comes with X, but we "drive" from the command line as we found DrRacket too slow on RPi. Essentially, students develop Racket using DrRacket on their desktops / laptops and then upload the file to the Raspberry Pi, where it is executed from the command line.
