I don't know, Ben, but you were probably directing the question to
Thomas and/or John.

Hello Thomas,

After providing Octave with the version-specific paths to the /m direc-
tory, I haven't (at least so far) run across any functions that can't be
found.

I took a look at both these files and noticed the path references to
    bin/octave-3.0.0
and lib/octave-3.0.0.  The reference to
include/octave-3.0.0 was commented out, but I didn't try to grok the
logic of whether these .cc and .h files were even needed for Octave's
operation.

Here's my .octaverc file, cosmetically modified so the path line shows
the paths on different lines (otherwise it would have been over 3000
characters long - just concatenate all those lines to get the original):
