Bad news. Nobu failed to reproduce this issue.

Could you try to build preview1 without ruby-build?

I can reproduce it doing the build manually with (({./configure; make})). Logs attached. gcc version:

Reproduced with Lion & default gcc: "i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)"
(comes from Command Line Tools (OS X Lion) for Xcode - October 2012, xcode451cltools_10_76938201a.dmg)

But can't with gcc-4.2 "i686-apple-darwin11-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5666) (dot 3)"

The gcc-4.2 is llvm-gcc, use clang.
If rbenv forces to use llvm-gcc, this issue should be reported to rbenv.
