is rb-gsl dead

[simon-dedeo]

Hello all — I was trying to install rb-gsl, and running into various issues. Among other things, it looks like it is no longer keeping up with gsl versions. gsl 2.8, for example, doesn't work; even after fixing warnings, we get errors like this

bspline.c:101:39: error: no member named 'k' in 'gsl_bspline_workspace'
    B = gsl_vector_alloc(w->nbreak+w->k-2);

which suggests to me that the underlying gsl code has changed sufficiently that things are broken. It's potentially possible to keep things going, but it does worry me that errors might be sneaking in that we don't see.

It would be sad to lose ruby support for mathematics, but if anyone knows of a project that is working well, do please share.
