I have not hacked around there.  I will have a look at it.  My  
thoughts are that to do the job properly it should all be conditional  
of f95 being requested.

I did not need anything to tell the build system where mine was in / 
usr/local.

The compiler as at the gcc-4.0.0 release has a major problem which is  
described in the documentation.  It cannot build a function with  
alternate entry points.  A patch for this (PR13082) was committed to  
the cvs on 29 April.  I have added this patch manually to the Apple  
gcc-5013 code and it seems to work.  It will now build Octave which  
was not possible with gcc-4.0.0 release version.

Apple's developer tools contain a nice GUI package maker which wraps  
the code up with any install scripts you want.  Disk images can be  
made with Disk Utility from /Applications/Utilities.  Everything is  
well documented.

Don't go there.  The Apple utilities are much easier to use.
