--------------
Faça:
1 - procure o arquivo libiconv.2.dylib (use o finder)
2 - Crie uma pasta lib em  /opt/local/ (faça isso num terminal como root)
3 - copie a lib para esta pasta

Acho que isso ocorreu porque essa libiconv.2.dylib é uma lib de C muito importante. Acho que foi depois de uma atualização do Mac OSX.
