Компиляция C++ — GSL на x86_64

Я пытаюсь скомпилировать следующий код: http://www-personal.umich.edu/~mejn/dcbm/KLOptimization.cpp

Но я получаю следующее сообщение об ошибке от g++:

> Undefined symbols for architecture x86_64:   "_gsl_rng_uniform_int",

У меня MacBook Air с iOS 10.7.3. g++ — это i686-apple-darwin11-llvm-g++-4.2.

Я установил GSL, используя «brew install gsl», что дало следующий результат:

Warning: m4 macros were installed to "share/aclocal".
Homebrew does not append "/usr/local/share/aclocal"
to "/usr/share/aclocal/dirlist". If an autoconf script you use
requires these m4 macros, you'll need to add this path manually.
