It would be interesting to hear what the error is, but yes, it sounds like
file-level conflicts. However, the fact that you get them for files you
haven't even touched:

You really shouldn't get any conflicts for anything you haven't touched,
since your starting point and the thing you are mergeing to are related,
so they shouldn't have any issues.
One common error people have is that the "merge" binary isn't in their
path, and the actual error is that the first path you _did_ touch failed
to do a three-way merge, and the merge simply has never happened.
If you do _just_ "merge" (no "git", no aguments, no _nothing_), do you get
a message like
merge: not enough arguments
merge: usage: merge [-AeEpqxX3] [-L lab [-L lab [-L lab]]] file1 file2 file3
merge aborted
(which is ok) or do you get a message like
bash: merge: command not found
(which means that you don't have a three-way merge at all)?
If you don't have the merge command, install the rcs package.

That's the "stage1" and "stage2" results. The SHA1's are identical, so it
should merge beautifully, and it does sound like the merge was never even
really attempted.
So
- do a "git reset --hard" to undo the partial (undone) merge
- do "yum install rcs" (or apt get, or whatever) to make sure that you
have the three-way merge binary.
- if it still doesn't work, please make sure to save all the error
messages so that we can see them..
Thanks,
Linus
