Error compiling root on OS X 10.10.3

Dear Rooters

On OS X 10.10.3 with newest XCode 6.3.1 I can not compile root_5.34.30, I get the following error:

The beginning of my config file looks as follows:

Can someone tell me why I do get this error?

Thank you in advance
Best regards,

Setting in .bashrc


did solve the problem.

Sorry for the confusion,
