This seems to be caused by a (new?) default use flag "three", which pulls in =dev-haskell/transformers-0.3.0.0-r1 and effectively tries to downgrade this package. Disabling this USE flag fixes the update process.

dev-haskell/transformers-compat has the USE three, which should be deactivate for workaround this problem. thanks volkmar dev-haskell/transformers-compat -three
Yeah, that flag is a disaster. .cabal file defines them because cabal can't infer used transformers directly from 'if / else if' maze. In portage we can (and should) set flags to whatever portage resolved ransformers depends to. The patch does exactly that: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=abd62b5cbd3b0d322f310e6f546479e4b1caafc8 Thanks for the report!
