Closed issue by kozross on void-packages repository

https://github.com/void-linux/void-packages/issues/11388

Description:
### System

* xuname:  
  *Void 4.19.36_1 x86_64-musl GenuineIntel notuptodate rFF*
* package:  
  *stack-1.9.3_1*

### Expected behavior

`stack setup` should download relevant GHC locally, as well as set everything up so I can do some Haskelling.

### Actual behavior

[Log from `stack --verbose setup`.](https://github.com/void-linux/void-packages/files/3129350/stack.log.gz) In short, this fails with a very weird error message.

### Steps to reproduce the behavior

```sh
stack new foo
cd foo
stack setup # add --verbose to get my log
```
