Hello guys, accelerate 0.12.1.0 (the one currently on hackage) depends from ghc-prim == 2., but this creates problem with modern base installation, making everything fail. The fix should be trivial, allow ghc-prim to be >= 2. in the manifest, as you did for 0.13.
It should be simple enough to make a patch release; I'll investigate. This slipped under the radar because I had intended to make a release for 0.13 before the new year (oops...).
Not only is it an easy fix, but the 0.13 already works; it's just a matter of releasing the new 0.13 package on Hackage :)
Released! (finally, apologies for the delay)
