I tried to build app-text/pandoc[https,network-uri]. Previously no haskell packages had been installed on my system. Compilation failed with: Data/Aeson/Encode/ByteString.hs:28:18: Could not find module ‘Data.ByteString.Builder.Scientific’ Perhaps you meant Data.ByteString.Builder.Extra (from bytestring-0.10.6.0@bytes_5uxHMIZkNTp9O0tsdC8daM) Data.ByteString.Builder.Internal (from bytestring-0.10.6.0@bytes_5uxHMIZkNTp9O0tsdC8daM) Data.ByteString.Builder.Prim (from bytestring-0.10.6.0@bytes_5uxHMIZkNTp9O0tsdC8daM) Use -v to see a list of the files searched for. After installing dev-haskell/scientific[bytestring-builder], the resume failed with: There are problems in package attoparsec-0.13.0.1: Warning: haddock-interfaces: /usr/share/doc/attoparsec-0.13.0.1/html/attoparsec.haddock doesn't exist or isn't a file Warning: haddock-html: /usr/share/doc/attoparsec-0.13.0.1/html doesn't exist or isn't a directory dependency "scientific-0.3.3.8-9ceeeb0e6706733b02c25c1908ec1519" doesn't exist Added doc useflag to dev-haskell/attoparsec and reinstalled dev-haskell/attoparsec. Afterwards the installation of dev-haskell/aeson and subsequently app-text/pandoc ran fine. Please let me know if you need further information.
Ah, nice catch! Pushed missing depend as: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=0bd289fd60312e3d218a888094cc3471c3ba3c78 Thank you!
