Probably because the CentOS 7 Singularity recipe is missing bzip2-devel.

Dropped use of bz2.

Not sure if this is the best solution? I’ve run into the same error with other Python-based distributions where I compiled the Python interpreter on my own machine. It seems that quite a few PyPI packages (e.g. MatplotLib) implicitly expect bzip2 to be there. If the bzip2-devel headers are present on the build machine a “vanilla” Python compiler will build the support library; if not it will just silently skip it.
