When emerging dev-lang/ghc-6.12.3, the configure step attempts to get version information from the bootstrapping compiler, and fails because it will not run (its dependent on libncursesw which is not installed) ldd /var/tmp/portage/work/ghc.../lib64/ghc shows unsatisfied libncursesw dependency Reproducible: Always Steps to Reproduce: 1. USE=-unicode emerge ncurses 2. emerge ghc 3. Actual Results: ghc fails to build/install Expected Results: ghc being successfully installed, or crap out saying that a version of ncurses needs to be installed with unicode support
emerge --info and full build.log please
What USE flags are you using with GHC? This has arisen before with USE=binary (but we never ended up resolving how to fix it); I haven't heard of it being a problem with USE=-binary though.
Sorry it took me awhile to follow up.

Yeah. We'll add required dep on ncurses[unicode] when we update minimal EAPI for ghc ebuild. It's nontrivial as we rely on eclass functions' call order (EAPI dependant): in pkg_prerm(). This part will become way simpler when ghc-6.12.3 will go stable on all arches.
This still an issue - even though the 6.12.3 is on the 'x86' ebuild is on stable. eg. # /var/tmp/portage/dev-lang/ghc-6.12.3/work/usr/bin/ghc -? /var/tmp/portage/dev-lang/ghc-6.12.3/work/usr/lib/ghc-6.12.3/ghc: error while loading shared libraries: libncursesw.so.5: cannot open shared object file: No such file or directory
Still a problem today, please fix, possibly by making it depend on ncurses w/ +unicode.
Added mandatory dep in version starting from: > *ghc-6.12.3-r1 (27 Mar 2011) > > 27 Mar 2011; Sergei Trofimovich <slyfox@gentoo.org> +ghc-6.12.3-r1.ebuild, > +files/ghc-6.12.3-ticket-2615-linker-script.patch: > Migrated to EAPI=3: initial PREFIX support (based on work of grobian); > USE=unicode for ncurses is a required depend (bug #326237 by Josh > Cartwright and others). Added linker script support to workaround bug > #311361 by Maciej Piechotka. Thanks everyone!
