Hi folks,

I'm Andrew Janke; I've been doing some work with Homebrew and specifically
Octave lately.

Homebrew has not dropped Octave support. It has active users, so it'll stick
around for the foreseeable future. However, octave has been moved from the
main "homebrew" section to the "homebrew/science" tap. This is basically a
namespace change, as Homebrew reorganizes to handle its swelling ranks of
packages. To install octave now, you need to `brew tap homebrew/science`
before you do `brew install octave` or related packages.

That said, there's been bugs in some Octave dependencies, so it hasn't been
building for the past week or so. We're in the process of fixing that.
Here's the bug if you want to watch it.
https://github.com/Homebrew/homebrew-science/issues/132

Gyan, your particular problem is that octave depends on the package fltk,
which is hosted on easysw.com, and easysw.com goes down a lot. We just
checked in a fix for this today, downloading fltk from a more reliable
mirror. Do a `brew update` and this problem should go away.

So, give it a day for the remaining Octave build issues to sort out. If it's
still broken tomorrow, head over to the homebrew-science issue tracker (each
tap has their own issue tracker), see if any octave issues are still open,
and report your build failure as a bug if it doesn't look like one of the
open issues.
https://github.com/Homebrew/homebrew-science/issues/search?q=octave&state=open

There's a troublehsooting guide which lists places to get Homebrew help:
https://github.com/mxcl/homebrew/wiki/troubleshooting. For build failures
like this, the GitHub issue trackers are most appropriate, or the Freenode
IRC channel if you want fast response to a short question.

Sorry for the long-windedness.

Cheers,
Andrew
