[Nix-dev] updating pgf-tikz

[raffalli at univ-savoie.fr]

Hello,

I tried to upgrade pgf/tikz in texlive to version 2.10 (which I need to work).
I succeded from a tar.gz in the debian mirror, but never from the .tdf.zip from sourceforge. The nix expression
is not completely trivial, I managed to have an accepted [ unzip ] as buildInputs,
but I got "unzip command not found". 

The download page is: http://sourceforge.net/projects/pgf/

And the nix file with a working .tar.gz is attached.

Cheers,
Christophe

    longDescription = ''
      PGF is a macro package for creating graphics.  It is platform-
      and format-independent and works together with the most
      important TeX backend drivers, including pdftex and dvips.  It
      comes with a user-friedly syntax layer called TikZ.

      Its usage is similar to pstricks and the standard picture
      environment.  PGF works with plain (pdf-)TeX, (pdf-)LaTeX, and
      ConTeXt.  Unlike pstricks , it can produce either PostScript or
      PDF output.
