Ruby GSL на OS X - рубин

Опитвам се да инсталирам Ruby GSL на OS X 10.9. Използвам Ruby 2.0.0, инсталиран чрез RVM. Според него място, Първо се нуждая от GSL. С това използвах Homebrew, за да инсталирам GSL (brew install gsl). След това го направих gem install gsl, но е получил това съобщение за грешка:

Някаква идея как да се определи това?

Отговори:

Последните версии на GSL вече не включват препратките backward и forward, заменяйки ги с gsl_fft_forward и gsl_fft_backward, и gsl_wavelet_forward и gsl_wavelet_backward.

Опитайте да приложите тази кръпка, която замества старите enums с новата: https://github.com/mvz/rb-gsl-nmatrix/commit/fe7643cd3026690f7de527b2a220c24330a85018
