Python 3.6 on Centos 6

[thinkwell]

I'm trying to build Python 3.6 on Centos 6, and am successful in doing so, except for the sqlite3 library. I started with a brand new install of Centos 6 and installed devtoolset-2 to build with a newer compiler. But whether with default compiler or 4.82, I get the following errors when building the sqlite3 module. sqlite & sqlite-devel are installed.

Any help for me in getting python 3.6 built on Centos 6?
