git-annex/standalone/android/haskell-patches/crypto-numbers_build-fix.patch
androidbuilder 34c6e0ea1a reverted updates to new lib versions that broke android build 
I ran into several evilsplicer problems with the new lib versions, most notably including a problem with encoding of embedded binary files
