In darktable's export module, OpenEXR is an option, and when run as a 
standalone, darktable does export OpenEXR images that GIMP can open:

magic match 4 on file-exr-load
best magic match on file-exr-load

It looks like darktable (installed though Gentoo portage) is not 
installed with Lua support:

$ darktable --version
this is darktable 2.0.3
copyright (c) 2009-2015 johannes hanika
darktable-dev lists darktable org

compile options:
  normal build
  OpenMP support enabled
  OpenCL support disabled
  Lua support disabled
  Colord support disabled
  gPhoto2 support enabled
  GraphicsMagick support enabled

It's not clear to me why Lua support is disabled. I do have Lua installed:
$ equery list '*lua*'
[IP-] [ ] dev-lang/lua-5.1.5-r3:0

There is no Gentoo use flag for darktable that allows to disable Lua 
support, and during ./autogen.sh, GEGL does list Lua as available and 
configured.
