When search finds a file that matchs with the fileName argument of findExecutable, it doesn't check if the file is an executable file.
do path <- getEnv "PATH" search (splitSearchPath path) where fileName = binary <.> exeExtension search :: [FilePath] -> IO (Maybe FilePath) search  = return Nothing search (d:ds) = do let path = d </> fileName b <- doesFileExist path if b then return (Just path) else search ds
findExecutable mustn't returns a file that it isn't an executable file, for example
(~/bin is in PATH variable)
$ touch ~/bin/foofile $ ghci $ :m System.Directory $ findExecutable "foofile"
shows that findExecutable returns IO (Just "/home/iago/bin/foofile").
Altought is not a bug, could be good add a new funcion (findExecutables for example) to return all the executables in all the paths of PATH variable that matchs with a given filename (like which -a).
