install problems

[Harold Zintel]

I'm trying to install the tsa package into Octave on a MacBook (intel) 
running osx10.5.5. 



octave-3.0.3:1> pkg list
Package Name   | Version | Installation directory
---------------+---------+-----------------------
miscellaneous *|   1.0.7 | /Users/haroldzintel/octave/miscellaneous-1.0.7
       optim *|   1.0.3 | /Users/haroldzintel/octave/optim-1.0.3
      signal *|   1.0.8 | /Users/haroldzintel/octave/signal-1.0.8
        time *|   1.0.8 | /Users/haroldzintel/octave/time-1.0.8
         tsa  |   4.0.0 | /Users/haroldzintel/octave/tsa-4.0.0


octave-3.0.3:8> pkg install tsa-4.0.0.tar.gz
error: the following dependencies where unsatisfied:
  tsa needs nan >= 1.0.0
octave-3.0.3:8>

The tsa in the pkg list was installed using -nodeps but the function I'm 
trying to use, lpc, isn't recognized.  'nan' is recognised but I don't 
know how to tell if it is >=1.0.0
