Ahem, you both are fast: I was commenting on the first patch, and
suddenly found that the third revision is already pushed :-)
Anyway, some comments:

Indentation of 'python-lirc' is not perfect:

> +(define-public python-lirc
> + (let ((commit "4091fe918f3eed2513dad008828565cace408d2f")
    ^^
should be moved one char to the right:

> +  (package
     ^^^
Likewise (you did it right in 'python2-lirc' package):

(define-public python-lirc
  (let ((commit "4091fe918f3eed2513dad008828565cace408d2f")
        (revision "1"))
    (package ...)))

This is not a tarball, but a directory (git checkout) so it is a strange
name for it.  We usually name such things like this:

  (file-name (string-append name "-" version "-checkout"))

this (modify-phases ...) should be shifted one char left

I don't think the description should begin with "@code{lirc}" as it is
not LIRC itself but a python library for LIRC.

the same as above
