It seems the file Here.txt must already have been added to git-annex before this point ... or whereis would not show it. Did you leave out a step? Was the file already added? Are you using direct mode?

The repository is a direct mode one.
I think there's something in your comment though; the content (\"1\") had already been added to a file (since deleted on dionysus),
however it does seem a bit inconsistent.

@edheil, you used to be right about the middleman. But I'm continually improving things. :)
So, consider this situation:
> A (client) --- B (client) ---- C (archive)
If a file is created on A, inside an `archive` directory, B wants a copy, since it's not archived yet. Once B gets the copy, it sends it on the C. At that point, B notices that hey, this file was archived and is in an archive directory, and so it no longer wants its copy and drops it.
(At this point A will also want to drop the file. However, it cannot! This is because git-annex requires positive, direct verification that some other repository has a file before dropping it, and A cannot talk to C to check.
However, if you set C to be trusted, this verification is bypassed, and then A will be able to drop the file as well.)
This support for middlemen is a new feature, which will be in the next release. You can get it in any recent nightly build.
Amusingly this feature was built without writing any haskell code.. just fine-tuning the preferred content expressions!
We can also consider what happens if B is set to manual. In this case, it won't automatically get the file from A. But if you manually get it, then B will send it on to C. And A will drop the file once it hears that C has it. Due to the manual mode, you'll have to manually drop it from B of course.

@Bret, the assistant relies on FSEvents pretty heavily. It seems to me your best bet is to upgrade OSX to a version that supports FSEvents.
You can certainly use the rest of git-annex on Snow Leopard without FSEvents.
