libstdc++ configuration error, ct-ng v1.16.0

[Michael Franklin <mfranklin at comfile dot co dot kr>]

Hello,

I'm having trouble understanding an error I'm receiving in the 
'Installing final compiler for build' stage.  It occurs when configuring 
libstdc++.  I'm hoping one of you swell folks would be willing to help 
me decipher it and maybe suggest a solution.  (See build log below)

I'm trying a Canadian Cross, and here's my setup
Build machine:  Linux Mint 64 (resident GCC)
Host: x86_64-w64-mingw32 (mingw-w64 packages installed with Synaptic 
Package Manager)
Target: arm-none-eabi

I've installed just about all packages with mingw and w64 in the name, 
so I think I have all the necessary tools, headers, and libraries.  Also 
I've already built an arm-none-eabi Linux Mint compiler without any 
trouble (Thanks to the crosstools-ng community for making it so easy)

It appears to me I'm missing some headers, but I think the headers just 
can't be found.  Maybe one of you can help me understand a little better.

Thanks,
Mike


Here's out output from the build.log.
