Can I have your ``emerge info'' please?

I feel much the fool.  As I was pasting the output of emerge-info, I realized
the offending option was in my make.info.  I thought that I had checked that.  

Thanks for the help.

Mike, you seem to be sort-of maintaining flag-o-matic so could you have a look
why this didn't get filtered and caused a failure as a result? Thanks...

this should be fixed in upcoming portage
