As an oversight this distro did not have bzip2-devel installed, so the pythons built by the toolchain do not provide bz2. It's since been installed and the python configure script is now capable of auto-detecting and enabling the bz2 module.

Since this is a no-code change I went to go restart the latest toolchain version for this distro but it broke partway through:

Would appreciate any help in how to fix that and get a rebuilt toolchain for rhel7-z
