So PPL did find GMP, it just didn't build.

Have to be clear in what the problem is and give some errors and any  
deviations from the book.

Yes, a patch is required for that. Be careful about upgrading  
toolchain packages like that with the stable book.

This was your first message:

checking for the GMP library version 4.1.3 or above... no
configure: error: Cannot find GMP version 4.1.3 or higher.
GMP is the GNU Multi-Precision library:
see http://www.swox.com/gmp/ for more information.
When compiling the GMP library, do not forget to enable the C++  
interface:
add --enable-cxx to the configuration options.

Which means you weren't using GMP 4.1.3 or greater?  If you were using  
the book's version and didn't do any strange deviations, the problem  
wouldn't occur.

But now, you say it found it, but had an error during make, which  
means you were using GMP 5.1.x, instead of GMP 5.0.x.

Not sure what was going on there, but glad you fixed the problem.

Sincerely,

William Harrington
