libgpp4-dev 1.3.1-0ubuntu2 (powerpc binary) in ubuntu saucy

 The goal of the ggp4 project is to provide a standalone replacement for
 the CCP4 library for macromolecular crystallography. The library performs
 a number of common tasks in standardized manner. These tasks include file
 opening, parsing keyworded input, and reading and writing of standard data
 formats for electron density maps and X-Ray diffraction data. Programs may
 call this library to ensure compatibility with the CCP4 program suite, as
 well as a similar look-and-feel.
 .
 This package provides header files and library for developing free
 CCP4 compatible programs.
