Hi, project devs

I have encountered a problem when compiling boost statechart viewer examples located at examples directory. The error output is attached in the email. Can you have a look at it?

My environment is 

clang version 3.4.2 (tags/RELEASE_34/dot2-final)

Target: x86_64-apple-darwin13.4.0

Thread model: posix

Thanks in advance!

Best regards.
