koji build error libtinfo.so.5

[Brennan Ashton]

I have been noticing this in all the root.log for builds on koji both
in F10 and F11:

DEBUG util.py:250:  /bin/sh: error while loading shared libraries:
libtinfo.so.5: cannot open shared object file: No such file or
directory
DEBUG util.py:250:  error: %post(bash-3.2-30.fc10.ppc) scriptlet
failed, exit status 127

It does not appear to be fatal, but what is going on?

Regards,
