[cfe-dev] Building libc++ on Lion

[Jean-Daniel Dupas]

Is there any change you get a custom version of libc++abi.dylib somewhere in the linker search path ? 
When I build libc++ using the default Lion's libraries, I don't get any error.

I'm not hugely familiar with all of these compiler options, so before I start investigating, I was wondering if this is something people have been running into. I've only been subscribed to the mailing list for a couple weeks, so I apologize if this is a worn out topic--my attempts at google searches have not turned up anything.
