MacOS – Installing Octave with Brew in Lion

errorhomebrewmacos

my first question on AskDifferent! (let me know if I'm doing it wrong.) Anyway, I'm trying to install octave using brew and am getting the following error but unsure how to proceed:

 ~/ brew install octave
==> Installing octave dependency: cmake
==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/cmake-2.8.7

################################################################## 100.0%

Error: SHA1 mismatch
Expected: f218ed64ce6e7a5d3670acdd6a18e5ed95421d1f
Got: 3a57f6f44186e0dba34ef8b8fb4a9047e9e5d8a3
Archive: /Users/Billy/Library/Caches/Homebrew/cmake-2.8.7.bottle.tar.gz
(To retry an incomplete download, remove the file above.)

 ~/

Any help would be greatly appreciated.

Best,
B

You seemingly have a bad download in the cache. Do this:

rm /Users/Billy/Library/Caches/Homebrew/cmake-2.8.7.bottle.tar.gz

And then try again. Make sure you're up-to-date first: brew update.
