Sabayon Problem

Hey !

I'm working on Sabayon (Gentoo), & i've installed Intellj without any problems.
I've DL the SDK, the SDK & JDK are in my PATH.
I've update the SDK.
But, when I try to launch my program (to test, i've created a helloWorld like) but there are an error :

Waiting for device.
/home/sidd/adt-bundle-linux-x86_64-20130917/sdk/tools/emulator -avd Tab -netspeed full -netdelay none

NAND: could not write file /tmp/android-sidd/emulator-nIAMHr, File exists

I've CHMODed my tmp file (on adt-bundle-linux.../sdk), but nothing...

Any idea?

Thx, (& sorry for my english... i'm french, that's my scuses)
Bastien.
