I have more information. I removed rvm totally from this machine and reinstalled both 1.9.2 and 1.9.3. Both versions now show this problem (previously 1.9.2 worked). These are the first interpreters I have installed since upgrading this machine to Lion. So I tried it on my laptop, also running Lion. Both 1.9.2 and 1.9.3 work there. This appears to be a local configuration issue on my machine. Sorry for the false alarm.

This may or may not be relevant, but the newest versions of Xcode (4.2 and/or 4.2.1) don't seem to install gcc-4.2 at all (only the llvm-gcc). It may be that you're seeing problems due to the compiler being different on the two machines?
