[yocto] question about SmartPM install from local file

[JC]

Hi,

I'm trying to get a better hand on how smart work. I've been successful 
to create a repo, update and install from it. Now I want to go further. 
Let's assume:
- I have a working repo and a working device
- I build a new recipe (here, git) and update my repo
- I "smart update" on my device
Now instead of installing, I choose to "download" the package :

# smart download git

It's successful. Now I want to install it :

# smart install ./git-1.8.1.4-r0.armv6_vfp.rpm
Loading cache...
error: Unable to create channel for file: ./git-1.8.1.4-r0.armv6_vfp.rpm

Whatever I do I end up with this error.

Does it ring a bell to anyone? Is this the right place to ask?

Thanks a lot for your help
Regards
Jay
