Comment (by talksense101@…):

 Atlas is still a problem with Port version 2.3.1 and Octave 3.8.1.  I
 cancelled the build after 7 hours on a Macbook Pro (2.3GHz i7 with 8GB
 memory).  The build log was stuck on step 2.4.5.  I rebuilt with
 +accelerate so that I can get Octave, but the warning messages aren't very
 inspiring.

 -----
 WARNING: Dependency 'arpack' is installed with the +accelerate variant,
 using
 Apple's Vector Libraries which have some known bugs that can cause Octave
 to
 crash if using certain functions in arpack.  The +atlas variant does not
 have
 these issues with Octave, but does take many hours to compile even on
 modern
 hardware.

 WARNING: The +accelerate variant has been selected, using Apple's Vector
 Libraries which have some known bugs that can cause Octave to crash.  The
 +atlas
 variant does not have these issues with Octave, but does take many hours
