For some reason I had to start the darcs emerge 2 times to get regex posix: >>> Installing (8 of 10) dev-haskell/regex-posix-0.72.0.2 >>> Failed to install dev-haskell/regex-posix-0.72.0.2, Log file: >>> '/var/tmp/portage/dev-haskell/regex-posix-0.72.0.2/temp/build.log' *** Resuming merge... * emerge --keep-going: dev-util/darcs-2.0.2 dropped due to unsatisfied * dependency. * emerge --keep-going: dev-haskell/regex-compat-0.71.0.1 dropped due to * unsatisfied dependency. * Messages for package dev-lang/ghc-6.8.2-r1: * IMPORTANT: * If you have upgraded from another version of ghc, please run: * /usr/sbin/ghc-updater * to re-merge all ghc-based Haskell libraries. * To enable command-line completion for ghc, run: * * eselect bashcomp enable ghc * * to install locally, or * * eselect bashcomp enable --global ghc * * to install system-wide. * Messages for package dev-haskell/regex-posix-0.72.0.2: * * ERROR: dev-haskell/regex-posix-0.72.0.2 failed. * Call stack: * ebuild.sh, line 1748: Called die * The specific snippet of code: * preprocess_ebuild_env || \ * die "error processing environment" * The die message: * error processing environment * * If you need support, post the topmost build error, and the call stack if relevant. * A complete build log is located at '/var/tmp/portage/dev-haskell/regex-posix-0.72.0.2/temp/build.log'. * The ebuild environment file is located at '/var/tmp/portage/dev-haskell/regex-posix-0.72.0.2/temp/environment'. * * Messages for package dev-util/darcs-2.0.2: * emerge --keep-going: dev-util/darcs-2.0.2 dropped due to unsatisfied * dependency. * Messages for package dev-haskell/regex-compat-0.71.0.1: * emerge --keep-going: dev-haskell/regex-compat-0.71.0.1 dropped due to * unsatisfied dependency. * * The following 3 packages have failed to build or install: * * ('ebuild', '/', 'dev-haskell/regex-posix-0.72.0.2', 'merge') * ('ebuild', '/', 'dev-util/darcs-2.0.2', 'merge') * ('ebuild', '/', 'dev-haskell/regex-compat-0.71.0.1', 'merge') -------------------------------------- >>> Verifying ebuild manifests >>> Starting parallel fetch >>> Emerging (1 of 3) dev-haskell/regex-posix-0.72.0.2 >>> Installing (1 of 3) dev-haskell/regex-posix-0.72.0.2 >>> Emerging (2 of 3) dev-haskell/regex-compat-0.71.0.1 >>> Installing (2 of 3) dev-haskell/regex-compat-0.71.0.1 >>> Emerging (3 of 3) dev-util/darcs-2.0.2 -------------------------------------- The only difference between the two runs was that in the second I emerged with LC_ALL=C to get english error messages.

Closing at INVALID. Please reopen the bug if I'm mistaken. Immediately after ghc upgrade user has to run ghc-updater/haskell-updater by hands to get nonbroken haskell system. Currently there is no way to stop portage from emerging stuff and give user a change to start ghc-updater/haskell-updater. At least I don't know such thing.
