Comment(by dave@…):

 Huh?  What affected port?

 I'm trying to build gcc from source using macports' libiconv.

 The build is invoked this way:

 {{{#!bash
 ~/src/gcc/configure --enable-languages=c,c++ --disable-multilib --disable-
 bootstrap --prefix=/usr/local/stow/gcc-4.7 --with-gmp=/opt/local --with-
 mpfr=/opt/local --with-mpc=/opt/local --without-libitm
 gmake
 }}}

 And fails as follows:

 {{{

 }}}

 The build is fixed by compiling and installing my own libiconv in
 /usr/local and using that one.
