ncurses breaks gawk trying to build py27-wxpython

[Dave Curtis]

Ah ha!  file shows some curious results...
{ my comments }

david-curtiss-macbook:wxtab dave$ which file
/usr/bin/file

{ Yup, that's the 'file' we want...} 

david-curtiss-macbook:wxtab dave$ file /opt/local/lib/libiconv.2.dylib
/opt/local/lib/libiconv.2.dylib: Mach-O 64-bit dynamically linked shared library x86_64
david-curtiss-macbook:wxtab dave$ file /opt/local/bin/gawk
/opt/local/bin/gawk: Mach-O 64-bit executable x86_64

{ The above work fine.  Let's see what the bad one looks like. }

david-curtiss-macbook:wxtab dave$ port installed libiconv
The following ports are currently installed:
  libiconv @1.13_0
  libiconv @1.13.1_0
  libiconv @1.14_0 (active)
  libiconv @1.14_0+universal
david-curtiss-macbook:wxtab dave$ sudo port activate libiconv at 1.14_0+universal
--->  Deactivating libiconv @1.14_0
--->  Cleaning libiconv
--->  Activating libiconv @1.14_0+universal
--->  Cleaning libiconv
david-curtiss-macbook:wxtab dave$ 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 ppc7400):	Mach-O dynamically linked shared library ppc
/opt/local/lib/libiconv.2.dylib (for architecture i386):	Mach-O dynamically linked shared library i386

{ Now, that looks pretty wacky.  What gives with ncurses trying to pull that cruft in? }

>>> 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.
