[basabuber]

As part of building eta, http://eta-lang.org/docs/html/getting-started.html, the build from source fails with the following error:

Build env: stack: 1.4.0 on Ubuntu: 16.10. Is this a ghc-paths issue?

Is there a known workaround to this?

[rahulmutt]

Should be resolved now, see https://github.com/typelead/eta/issues/246.

[tonymorris]

I can confirm that it now works for me. Thanks @puffnfresh and @rahulmutt
