I really want to use +Inf there, not 1e20. In my version of Guile (1.8.1), "inf" is a built-in function that returns the IEEE infinity value. Apparently "inf" is not present in older versions of Guile, and in particular in Guile 1.6.x, hence your error. A workaround is to replace (inf) with (/ +0.0), which does the same thing. I just checked that it seems to work fine in Guile 1.6.x and in Guile 1.8.x. I'll probably release a version 0.20.2 shortly to fix this problem.
