libgsl-dbg 2.1+dfsg-2 (powerpc binary) in ubuntu xenial

 The GNU Scientific Library (GSL) is a collection of routines for
 numerical analysis. The routines are written from scratch by the GSL
 team in C, and present a modern API for C programmers, while allowing
 wrappers to be written for very high level languages.
 .
 This package contains debugging symbol tables for the static GSL libraries
 libgsl and libgslcblas from the libgsl0-dev package, and the binaries
 gsl-randist and gsl-histogram from the gsl-bin package.
