I get the following error when trying to build reflex for an Etlas project.
I am quite new to this, could you help me figure out if a patch is needed?
Here is part of the log:

Configuring library for haskell-src-exts-1.20.3..

Please report this as a Eta bug: http://github.com/typelead/eta/issues

etlas: Failed to build haskell-src-exts-1.20.3

@Zenleaf Yes, haskell-src-exts requires a patch to split code into separate files until we find an automated way to fix the problem. This was introduced in recent versions of Eta to let you know at compile-time that something will crash at runtime.

Awesome, thought so. Would like to give it a try when I have time.@rahulmutt
