As others have noted, this problem arises when upgrading math/py-numpy
because the PDFs across versions are not distinguishable by file name.
Cached distfiles are not replaced but fail the checksum step.
science/py-scipy has this problem too.

I've filed a bug report upstream for numpy, and will follow-up in due
course with an equivalent ticket for scipy.

In the mean time, the work-around is to manually delete
$DISTDIR/numpy-{ref,user}.pdf before upgrading. Until this is resolved
upstream (or if it never is), perhaps the maintainer would develop a
local versioning system, or accept a patch that implements one.
