lsof

[Andreas Enge <andreas@enge.fr>]

Hello,

the lsof tarball contains the source in a two-stage process: After 
unpacking, one is left with lsof_4.87_src.tar, which needs to be unpacked 
as well. I tried the following:

   (arguments
    `(#:phases
      (alist-replace
       'unpack
       (lambda* (#:key source name version #:allow-other-keys)
         (let ((unpack (assoc-ref %standard-phases 'unpack))
               (inner (string-append name "_" version "_src.tar")))
           (apply unpack (list #:source source))
           (apply unpack (list #:source inner))))
       %standard-phases)))

But apparently, NAME and VERSION are not passed through as function 
arguments (they are #f). Would it make sense to changes this? Or do you see 
a preferable way of doing the second stage unpacking?
