Hey, can you give some more info, like what are your deps, where are you using this, how did you get this error etc? Thanks!

Closing this as -

1. no details available
2. we just releases a major release of 0.4.0

If anyone is still facing compilation issues, I'd suggest using latest 0.4.* versions, or comment with more details so we can take a better look. Thanks :)
