When I try stack build --flag poppler:gtk3
 I get
=================
--  Failure when adding dependencies:
      hoodle-core: needed (>=0.15.0 && <0.16), couldn't resolve its
dependencies
    needed for package hoodle-0.4.999

      hoodle-publish: needed (>=0.2), couldn't resolve its dependencies

dependencies

      gtk3: needed (>=0.13 && <0.14), 0.14.2 found (latest applicable is
0.13.9)
    needed for package poppler-0.13.1 with flags:
      gtk3: True
=============
Happens whether I try more focussed:
$ stack build poppler --flag poppler:gtk3
get
=============
While constructing the BuildPlan the following exceptions were encountered:

--  Failure when adding dependencies:
      gtk3: needed (>=0.13 && <0.14), 0.14.2 found (latest applicable is
0.13.9)
    needed for package poppler-0.13.1 with flags:
      gtk3: True
================


[In cut pasting Ive elided oodles of stuff like:

No packages found in snapshot which provide a "gtk2hsC2hs" executable,
which is a build-tool dependency of "glib"
Missing build-tools may be caused by dependencies of the build-tool being
overridden by extra-deps.
This should be fixed soon - see this issue

This is the stack.yaml (without comments)
