[PD] pdp - where is libgsl?

[robcanning]

Hi,

I'm trying to get PDP running on osx 10.2.4 Darwin

after: ./compile
...
checking for main in -lgsl... no
ERROR: libgsl not found


i tried: sudo apt-get install  libgsl0-dev
E: Couldn't find package libgsl0-dev

all i can find when i google for it are .rpm  packages.

where can i find libgsl????

Thanks,

Rob
