Comment(by kitchen.andy@…):

 Hey Buddy,  it seems to maintain compatibility newer iconv.h
 hash defines iconv_open to libiconv_open.

 {{{
 --- from /opt/local/include/iconv.h line 70
 #ifndef LIBICONV_PLUG
 #define iconv_open libiconv_open
 #endif
 }}}

 So this error is caused by using the _new_ header
 but linking with the _old_ library, so LIBRARY_PATH
 was a red herring.

 What we really need to do is get the gcc that ghc
 is using to search /usr/include before /opt/local/include

 Try using the C_INCLUDE_PATH

 {{{
 export C_INCLUDE_PATH="/usr/include"
 }}}

 also -isystem

 {{{
 CCFLAGS="-isystem/usr/include"
 }}}

 Both should have the effect of making /usr/include
 searched first:

 {{{
