Graphics.Gloss.Data.Extent has moved from gloss to gloss-algorithms in gloss-1.9.1.1. All the examples include a cabal file which includes gloss-algorithms and requires gloss 1.9.2.1 or later.
Both cabal and stack should pick up that information from the cabal file, so I don't understand why that didn't work for you. Which tool did you use in order to compile the examples?
It looks like gloss does not expose Graphics.Gloss.Data.Extent interface since 1.9.1.1, hence examples do not compile with recent gloss versions.
