You diverted a conversion toward your own purpose. Please don't do that without 
changing the "subject" line.

Ok. Octave builds and runs using both the Fink and Macports package managers. 
It appears the problem is with the Homebrew formula. 

There is a bug report on the Homebrew web site that looks similar.

        https://github.com/mxcl/homebrew/issues/8099

The fix was to ...

        rm -rf ~/.fontconfig

If that doesn't fix the problem for you, I recommend you add an "issue" to the 
homebrew githup so that the individual maintaining the homebrew octave formula 
can help debug the problem.
