bootstrap.sh doesn't work?

[quickfur]

According to README.md, reggae can bootstrap itself just by running bootstrap.sh. However:

$ ./bootstrap.sh 
Compiling reggae with dub
(7): Error: Expected valid JSON token, got 'import    co'.
$

I'm not sure if it's expecting something in the environment that I just happen to be missing?

It works in CI, and I just ran it myself and it worked, I can't reproduce this.
