Gnudl should run nicely on any platform where guile compiles. I do development on linux, IRIX 5.3 and SunOS 4.1.4.
You can obtain gnudl from the anonymous ftp site nis-ftp.lanl.gov:pub/users/rosalia
But you must first install guile, available from
ftp.cygnus.com:pub/lord
Gnudl version proto2.4 compiles with the guile-iii snapshot, but you should take a look at Mark Galassi's notes on learning libguile since it describes how to solve some problems that come up when installing guile-iii.
Users in the NIS division computers in Los Alamos can make a directory for gnudl using the NIS division CVS repository:
setenv CVSROOT /n/projects/cvs
(or export
CVSROOT=/n/projects/cvs for bash users).
and then just type cvs checkout gnudl/proto4
