Installing Octave with Brew in Lion 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

  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,

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.
