>Description:
Compilation of lang/ghc fails with:

/usr/local/bin/ld: /usr/ports/lang/ghc/work/ghc-7.4.2/libraries/terminfo/dist-install/build/libHSterminfo-0.3.2.3.a(Base__103.o): undefined reference to symbol 't$
arm'
/usr/local/bin/ld: note: 'tparm' is defined in DSO //usr/local/lib/libtinfow.so.5.9 so try adding it to the linker command line
//usr/local/lib/libtinfow.so.5.9: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
gmake[1]: *** [ghc/stage2/build/tmp/ghc-stage2] Error 1


according to pkg_info -W, libtinfow is part of ncurses.

Seems related to this problem:

>How-To-Repeat:
Try building lang/ghc while devel/ncurses is installed on the system.
>Fix:
Delete devel/ncurses for the duration of the lang/ghc installation
