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?
