It's not enough to try to link against libiconv and look for a symbol iconv_open, because iconv may be installed in a way that internally renames iconv_foo to libiconv_foo in the library and adds corresponding #define iconv_foo libiconv_foo to iconv.h.

This patch is needed on OpenBSD (but it's not enough, since cabal suffers from the same problem).

Oops! The last sentence is a little bit misleading. The real problem seems to be the way haskeline's Setup.hs tries to check for libiconv (it doesn't use /usr/local/lib and /usr/local/include for libraries and include files even if you pass them via environment in LDDFLAGS and CPPFLAGS to configure for a complete ghc buidl). Is there any reason for haskeline not using autoconf?
