>>> The short answer is that you need to rebuild libiconv +universal, or follow the Migration instructions if applicable. This has come up so often on the list and in the issue tracker since Snow Leopard's release three years ago that it's time for me to write a ProblemHotlist entry for it. I'll reply here again when I've written it.

You can use the "file" command to see what architecture things are actually built for.

/usr/bin/file /opt/local/lib/libiconv.2.dylib
/usr/bin/file /opt/local/bin/gawk

On my system, with both ports built universal, I get this output:

$ /usr/bin/file /opt/local/lib/libiconv.2.dylib
/opt/local/lib/libiconv.2.dylib: Mach-O universal binary with 2 architectures
/opt/local/lib/libiconv.2.dylib (for architecture i386):	Mach-O dynamically linked shared library i386
/opt/local/lib/libiconv.2.dylib (for architecture x86_64):	Mach-O 64-bit dynamically linked shared library x86_64
$ /usr/bin/file /opt/local/bin/gawk
/opt/local/bin/gawk: Mach-O universal binary with 2 architectures
/opt/local/bin/gawk (for architecture x86_64):	Mach-O 64-bit executable x86_64
/opt/local/bin/gawk (for architecture i386):	Mach-O executable i386

What about you?
