You might want to try the octave-help mailing list
(help-oct...@octave.org), since that is focused on actually using
Octave, including building against it. Our lists are more focused just
to issues with building and installing packages under Fink, and this
doesn't necessarily look like it's a problem in how Fink builds Octave.
