Cannot remove/access warning during installation. Files bumblebee-enable(disable)card are missing

[DeeKey]

To reproduce:

1. Download latest sources MrMEEE-bumblebee-67e862b
2. Uninstall previous version of bumblebee
3. Install the new version
4. Observe installation log
5. Check if files exist:
   /usr/local/bin/bumblebee-enablecard' /usr/local/bin/bumblebee-disablecard'

Expected results:
4) No errors or warning in the log
5) Files exist

Actual results:
5) Warning in the log (see below)
6) Files are not present

Extract that contains warning from the full log:

Forgot to mention hardware:

Asus U36Jc.

OS: Ubuntu 11.04

BTW: Consider that U36Jc could also be added to the list of supported hardware:
10) Asus U30J/U35J/U43JC/U35JC/U43JC/U53JC/P52JC/K52JC/X52JC/N53SV/N61JV/X64JV

Installed from MrMEE . Files
bumblebee-disablecard
bumblebee-enablecard
are present. Though there are still some warning in the log.
Also I don't understand the sense of the latest comment...

[MrMEEE]

there errors shouldn't mean anything...

Does it work??

[DeeKey]

Files are present. Thus I can close the initial problem.
