new-build does not like gtk3-dependency

[lspitzner]

It seems to be independent of local cabal package.

(foo is local, has a direct dependency on gtk3, compiles fine when removing the dependency.)

cabal new-build -j1
In order, the following will be built (use -v for more details):
gtk3-0.14.2
foo-0.1.0.0

I think this is #3199. As a workaround, try passing --constraint="gtk3 +build-demos"

[lspitzner]

(ah, sorry for dup; i had filtered for nix-local-build.)

[ezyang]

I am not sure it is a duplicate. Did the workaround work?

Workaround confirmed to work, closing as dupe.
