Hi,

They look ok for me (not tested or applied yet).

One neat pick:

   #:use-module (guix packages)
+  #:use-module (gnu packages python-build)
   #:use-module (gnu packages check)
   #:use-module (gnu packages python-compression)
   #:use-module (gnu packages python-crypto)

It may be sorted as well.

Feel free to merge fixes fast ;-).
