math/octave doesn't see atlas

[[LoN]Kamikaze]

I have two systems and both want to install math/atlas when I try to update octave. I have atlas-3.6.0_2,1 installed on both systems.

===>   octave-2.1.73_2 depends on executable in : gnuplot - found
===>   octave-2.1.73_2 depends on executable in : gfortran42 - found
===>   octave-2.1.73_2 depends on executable in : gmake - found
===>   octave-2.1.73_2 depends on file: /usr/local/bin/perl5.8.8 - found
===>   octave-2.1.73_2 depends on shared library: fftw.2 - found
===>   octave-2.1.73_2 depends on shared library: atlas.1 - not found
===>    Verifying install for atlas.1 in /usr/ports/math/atlas
===>  Extracting for atlas-3.6.0_2,1
...

I don't know what might be the cause. What kind of information is necessary to diagnose what's going on?
