Note that salmonella uses an isolated local egg repository to test eggs,
so that it can catch dependency problems.  I'd guess the hahn-utils
executable you are using is from your CHICKEN installation prefix, not
from the environment that salmonella uses.  Is that correct?  If so,
that would explain why you can run hahn-utils but salmonella can't.

I don't know how hahn/hahn-utils work, but both seem to be ok according
to you test system [1][2].  It seems that you are using hahn-utils, but
you have hahn in your dependency specification.  According to the
dependency graphs, hahn-utils depends on hahn, not the other way around
[3][4].  It's possible that hahn is documented using itself, and that it
would optionally use hahn-utils (that would be a circular dependency),
but I'm not sure about that.

The documentation must be available in our wiki.  The test that checks
for the availability of documentation is basically a HEAD request.

All the best.
