I think your /etc/apt/sources.list  is severely broken. "build-essential"
is in the main repository - if you can't install it and apt says it can't
find the dependencies, ,your list of available repositories is almost
certainly at fault. 

I suggest you visit:

http://www.ubuntulinux.nl/source-o-matic  , follow the instructions there
carefully, and make yourself a new sources.list. Be sure to choose your
version ( dapper, breezy etc) carefully. 

I suggest only choosing the "supported" and "community supported" packages
from that URL


Move your present sources.list out of the way - for example

sudo mv /etc/apt/sources.list /etc/apt/sources.list.old

then replace it with the new one you get from the URL I posted. Finally run

sudo apt-get update

After that you should be able to install build-essential , and more or less
anything else - assuming you haven't done anything dangerous like using
3rd party or Debian repositories.

You should get a list something like the one I have pasted below, except
that this one does not specify a country code ( you will probably want to
have that as a nearby mirror is preferable, but the vanilla file I pasted
below should also work fine)
