installing toolchain

[TGreen@wencor.com]

Hi all,

I realize that I'm working on an ubuntu
system (fiesty), but thought that since it's a debian based system getting
the toolchain installed on it would be rather straightforward.  Unfortunately,
it doesn't work like that.  Using the instructions from http://www.emdebian.org/tools/crosstools.html
I added 

deb http://www.emdebian.org/debian/
unstable main

to my /etc/apt/sources.list.  
When I try to install the mipsel version of the toolchain I get the following:

tomg@squid:~/crosstools/trunk# sudo
apt-get install g++-4.1-mipsel-linux-gnu
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed.
This may mean that you have
requested an impossible situation or
if you are using the unstable
distribution that some required packages
have not yet been created
or been moved out of Incoming.

Since you only requested a single operation
it is extremely likely that
the package is simply not installable
and a bug report against
that package should be filed.
The following information may help to
resolve the situation:

The following packages have unmet dependencies:
  g++-4.1-mipsel-linux-gnu: Depends:
gcc-4.1-base (= 4.1.2-21) but 4.1.2-0ubuntu4 is to be installed
           
                Depends: gcc-4.1-mipsel-linux-gnu
(= 4.1.2-21) but it is not going to be installed
           
                Depends: libc6
(>= 2.7-1) but 2.5-0ubuntu14 is to be installed
           
                Depends: libstdc++6-4.1-dev-mipsel-cross
(= 4.1.2-21) but it is not going to be installed
E: Broken packages

Ok, so I'm a complete noob to the cross
compiler, but the installation should be straight forward enough.  How
do I get the proper versions of the tools installed?

TIA
