I'm having difficulty getting the eigs package to work with Octave.app 2.9.14 on my Macbook Pro with Mac OS X 10.4.10. I've been playing with Octave for a couple of months and it seems to work very well for the most part. I had no trouble installing the plot package version 1.0.2
The most recent string of complaints issed by Octave when I try to install is listed below.
