The symptoms make it look as though the *function* Blob is not exported.
I see in your source that you do export the *class* Blob, but the docs
don't make it clear to me that this also implies export of the generator
function.
So I'd add
export(Blob)
to your NAMESPACE. I just checked another package that exports a class,
and it separately exported the generator function, so I guess this is known.
