Try 'apt-get -f install' that will try to get the packages into a sane
state again.
Not sure what you did but you manged to install libgcc1 that requries
gcc 4.3 but not have gcc-4.3-base installed. So the answer is either
install gcc-4.3-base or go back to an older libgcc1 that you do have the
requirements for.
Be very careful since removing libgcc1 will likely make your system
unusable so don't do that. Either install an older version (apt-get
install libgcc1=someversionnumber), or install the required gcc-4.3-base
package.
'apt-cache show libgcc1 |grep Version' can get you a list of what
versions you have to choose between.
