I am seeing this error now, on a stable system where I have never seen it before!

@wbraswell unsupported version: 2.1.1 at t/00-load.t line 14. looks related, did you upgrade to GSL 2.1.1 and then do a partial recompile? That is going to confuse the heck out of our build system 😄

@leto
I thought the unsupported version thing might be a separate issue and have filed it as you can see above. I have not (purposefully) upgraded to GSL 2.1.1, I am checking now to see if Ubuntu experienced any such issues.
