See `config.log' for more details.
Although the error shown gives me an idea, details are missing. Did you have a look at the config.log file that was created?
My guess for now: You haven't (correctly) build c++ (this was done in chapter 5.10 GCC-4.5.2 - Pass 2).
If my assumption is correct fixing this isn't as easy as the previous perl problem you had. You already adjusted the toolchain (6.10) so going back to chapter 5, (re)installing gcc and continuing with 6.16 is probably not possible. You can, of course, try.
I do hope you followed the advise given at the bottom of chapter 5.34
. In that case you don't have to start from scratch again but can remove all and restore the backup. At this point you can redo 5.10 and all of chapter 6.
But do have a look at the config.log first!
Hope this helps.
