If I run the same command in $S, I get the same failure. But with

# /usr/bin/ghc -package Cabal --make /var/tmp/portage/dev-haskell/extensible-exceptions-0.1.1.4/work/extensible-exceptions-0.1.1.4/Setup.hs -dynamic -o setup
[1 of 1] Compiling Main             ( /var/tmp/portage/dev-haskell/extensible-exceptions-0.1.1.4/work/extensible-exceptions-0.1.1.4/Setup.hs, /var/tmp/portage/dev-haskell/extensible-exceptions-0.1.1.4/work/extensible-exceptions-0.1.1.4/Setup.o )
Linking setup ...

it seam to work.

Comment 7 Dominique Michel 2015-04-17 20:16:27 UTC

The line

CABAL_CORE_LIB_GHC_PV="7.4.0.20111219 7.4.0.20120126 7.4.1 7.4.2"

is not documented into the devman. I commented out that line and the ebuild worked.

You should really not remove that line. What ghc version you are running?

Running 'ghc-pkg recache' (or unmerging any random haskell package)
should tickle package cache to the state when haskell-updater can catch stuff.

The variable is not expected to be used in normal ebuilds:

Sorry for the delay. I missed the previous mail.

# ghc-pkg recache

Nothing to build!

If I merge it by hand, it just work now. Thank you, to run ghc-pkg recache fixed it.
