https://www.gnu.org/software/gsl/ says version 1.16 is the newest. Look at the timestamps within ftp://ftp.gnu.org/gnu/gsl/ and you'll see that 1.9 came out in 2007 while 1.16 is from last year. Generally-- is there some way to get a numeric human sort on that directory listing? Or to include a gsl-latest.tar.gz link as is done in other projects? - Rhys
