[Tinyos-help] AVR tools installation error

[Sun Chao]

Hello all:
	I intend to install the AVR tools on my Ubuntu system, but got the
following error:
Selecting previously deselected package avr-insight.
(Reading database ... 101921 files and directories currently installed.)
Unpacking avr-insight (from avr-insight_6.3-2_i386.deb) ...
dpkg: error processing avr-insight_6.3-2_i386.deb (--install):
 trying to overwrite `/usr/share/info/gdb.info.gz', which is also in
package gdbdpkg-deb: subprocess paste killed by signal (Broken pipe)
Errors were encountered while processing:
 avr-insight_6.3-2_i386.deb

I'v installed avr-binutils, avr-gcc, avr-libc and avarice according to
the instruction of
http://www.tinyos.net/tinyos-2.x/doc/html/install-tinyos.html
Does any one know what's wrong with this?
