No, it's ghc-7.4.2-x86_64-apple-darwin.tar.bz2 from haskell.org/ghc.

Turns out it's got nothing to do with vector per se. ghci doesn't work either (should have realized this sooner -- it's going wrong when TH initializes when building vector).

Is this a 32bit ghc? It's complaining about libiconv beig the wrong architecture.

Hi guys,

I am currently unable to build vector on OSX:
Loading package base ... <command line>: can't load .so/.DLL for: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/lib/libiconv.dylib (dlopen(/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/lib/libiconv.dylib, 9): no suitable image found.  Did find:
	/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/lib/libiconv.dylib: mach-o, but wrong filetype)
cabal: Error: some packages failed to install:
vector-0.10.11.0 failed during the building phase. The exception was:
This has been reported before as some kind of clang issue, but I am using gcc 4.8 (ghc-7.4.2/settings has "gcc-4.8" for "C compiler command"). 
Any suggestions?
Thanks!
