problem using rpm package

Hi all,
I am trying to create a rpm package.
In the spec file %install section

***
%install
mkdir -p /usr/local/flashupdt/drivers/
install -s -m 755 -o 0 -g mouse /usr/local/flashupdt/drivers/mouse
***

The install command creates a "mouse?" file in /usr/local/flashupdt/drivers/
intsead of mouse.

The same command works fine on command line.
I have also tried using cp command.
I am getting same results


Could you please tell me why this is happening?

Thanks,
Jitesh
