Argghhh!!! It was supposed to have gone to the list,  but I must have

Am I supposed to add the

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

line to my sources.list?  I've been under the impression that mixing
Debian repositories with Ubuntu repositories wasn't a good idea, and
have been attempting to figure out how to install the cross
development tools without that repository.

Perhaps that is the source of my problem.  (Although, when I tried
that, I still had the libmpfr4 problem).
