As a guile-hobbit maintainer, I can say that there is a 1.4.1 version,
functioning with guile of the same release. I use it regularly. At the
time of this last release (end 2000), I was unable to put the
sources to a public guile ftp server, so very few people use this
version, but now this may be possible ? 

I have even filled forms for the FSF to turn the copyright to them, as
I have no short term plan to upgrade hobbit to be 1.6 compatible. This
because I have no need to upgrade to a more recent guile version so far.

(I catch this mail in the middle of a vacation, so do not expect a fast
answer if interested in the 1.4.1 sources.)
