Comment (by essandess):

 I'm updating port ghc and this annoying {{{libiconv}}} issue bites me
 every time.

 The simple solution is to run

 {{{
 sudo port deactivate libiconv
 }}}

 before running {{{sudo port test ghc}}}.

 My preferred solution would be to prevent linking to
 {{{/usr/lib/libiconv.dylib}}} in the first place. I don't see why this
 happens—{{{LIBRARY_PATH}}} is already set to {{{/opt/local/lib}}} in all
 MacPorts stages.

 Does anyone know how to tell MacPorts to build {{{ghc}}}  without using
 the system {{{iconv}}} library?
