minor install bug fixes

[Stephan]

Upon the release of v2.0 I commented out some code before upload and
in doing so broke the code. I have fixed the minor issue and uploaded
a 2.0.1 release.

see:

http://code.google.com/p/fireshark/downloads/list

if you don't want to install everything again just need to replace
the fireshark daemon that's in /usr/sbin/ with the daemon/fireshark in
the download
