As an exercise before porting the up-to-date version of scmutils, I eventually decided to bring Daniel Gildea's Guile port up-to-date. You'll find the archive guile-scmutils-v0.8.tgz here: http://www.cs.rochester.edu/~gildea/guile-scmutils/ You should be able to apply the attached patch and then be able to run it under guile-2.0 Best regards, Mikael D.
