That's an arguably nicer way than how I solved it; I just removed 
the
bits causing the error since I didn't need them anyway:

https://github.com/magthe/amazonka/commit/1543b65e3a8b692aa9038ada68aaed9967752983

Then I used `stack` to point to my modified version. I wouldn't be
surprised if people on the list already know how, but just in case 
I'll
throw in a link to my description of it:

If you can tell the truth, you don't have to remember anything.
