[Tinyos-help] PySerial problem in Deluge T2

[Dan]

Hi, there,

Following the deluge T2 tutorial, I tried to test Quick Start on Iris.
When the command "./burn /dev/ttyUSB0 iris" was executed, an error
occured as follows:

Please install PySerial first.

I've installed the latest CVS and the python scripts following the
Tools Installation section. Any ideas? Thanks in advance.
