The initialization files are loaded in the order: 

.snd_prefs_guile, .snd_guile, .snd

If you set the load-path in ~/.snd by consing a path onto
the front of the list, that becomes the load-path reported
by the preferences dialog.  I do not touch any file except
the preferences output, so I can't fix this.  Another
possible "gotcha" here is that you need to type <return>
in the text widget for it to notice that its value has
changed.  So, if I understand the problem, either remove
the bad value from your ~/.snd file, or at least don't
make it the first thing in the load list.

Or, since you're using ~/.snd anyway, combine whatever
you want from the prefs output into ~/.snd and delete the
prefs file.
