difficulties with installing lispy and its dependencies via el-get

[toogley]

hello,

i tried to install the lispy package via 


  (package-initialize)
  (add-to-list 'package-archives '("melpa" . "http://melpa.org/packages/";))
  (setq el-get-sources
          (:name lispy
                 :type melpa
                 ;;:pkgname "abo-abo/lispy"
                 )
          ))
  (setq my/packages (append '(lispy)))
  (el-get 'sync my/packages)


=> Which produces the error "Error (el-get): while installing lispy: Unknown 
recipe type: :melpa"


When i change my init.el to:

  (setq el-get-sources
          (:name lispy
                 :type github
                 :pkgname "abo-abo/lispy"
                 )
          ))
  (setq my/packages (append '(lispy)))
  (el-get 'sync my/packages)

=> Which successfully installs lispy, but after setting "(lispy-mode 1)", I
receive the error "Cannot open load file: No such file or directory, avy", which

I can resolve if i manually set the dependencies of lispy like that:

  (setq el-get-sources
        '((:name org
                 :type git
                 :url "git://orgmode.org/org-mode.git"
                 )
          (:name lispy
                 :type github
                 :pkgname "abo-abo/lispy"
                 )
          (:name avy
                 :type github
                 :pkgname "abo-abo/avy"
                 )
          (:name iedit
                 :type github
                 :pkgname "abo-abo/iedit"
                 )
          (:name swiper
                 :type github
                 :pkgname "abo-abo/swiper"
                 )
          (:name hydra
                 :type github
                 :pkgname "abo-abo/hydra"
                 )
          ))
  (setq my/packages (append '(lispy avy iedit swiper hydra)))
  (el-get 'sync my/packages)


=> But that produces "Symbol’s function definition is void: defhydra" if i want
to set (lispy-mode 1)


What can I do to resolve this issue?
