Gsl ruby gem no Ubuntu Saucy (13.10)

Question

Estou tentando instalar a gsl gem no Ubuntu Saucy

Eu instalei os pacotes relevantes de gsl com

sudo apt-get install gsl-bin libgsl0-dev

Mas a instalação da gem falha

O problema é semelhante a este: Problemas na instalação da gsl gem

A solução principal desse segmento não funciona - o pacote fonte do gsl 1.14 não está mais disponível naquele endereço. Eu acho que isso será útil para muitos usuários com Saucy.

    

Answer 1

Para o Ubuntu 13.10, o ruby 2.0.0 funciona bem em seguida -

curl -O http://ftp.unicamp.br/pub/gnu/gsl/gsl-1.16.tar.gz
tar xvzf gsl-1.16.tar.gz
cd gsl-1.16
./configure
make
sudo make install
sudo gem install --conservative --no-ri --no-rdoc gsl
