It will try (at a minimum) to detect if the GSL library is installed on the local system. If not it will attempt, if possible, to download/build/install it. This build process will likely require the C<Build> script to be run with root privaledges. Future versions of L<Alien::GSL> may try to avoid this problem. This is not necessary if the library is already installed on the system.

A wrapper around C<gsl_version()> which (optionally) takes a number specifying a minimum GSL version, returns the GSL version if it is greater than or equal to that specified. Returns zero otherwise. May also be called with zero as the version parameter, or no parameter at all, in which case the behavior is the same as C<gsl_version()>.
