Hello, There was a bug in haskell-js-jquery (libghc-js-jquery-dev and libghc-js-jquery-data should be of the same version, but this dependency was not there) that caused haskell-shake to FTBFS. This has been fixed in haskell-js-jquery/1.12.4-2. Please give back haskell-shake on armel, armhf, i386, powerpc, kfreebsd-amd64 and kfreebsd-i386. gb haskell-shake_0.15.6+dfsg-1 . armel armhf i386 powerpc kfreebsd-amd64 kfreebsd-i386 Thanks, -- Ilias
