At this point, configure thinks you have the gcc compiler installed.

Now it's going to invoke the compiler to see what kind of output it
creates.

The gcc compiler is complaining that it cannot find the file cc1plus.
The problem appears to be with the installation of gcc. If gcc was
included in your default os setup, you may need to re-install it as
the default setup may not include all the options (such as installing
the c compiler but not the c++ compiler).

I ran into a similar problem with Cygwin. In the setup program you
have to specifically tell it which compilers to install. Which it does.
But it doesn't include the tools needed by similar configuration
programs such as make and m4. Those are in a different section
of the setup program and you need to know which ones to install.
There's no option for "install everything I need to compile c/c++
programs". In my case, I had to run configure over and over again
each time going through the log finding a new missing file, re-install,
and repeat until the errors stopped.
