Problems with compilation

[Uwe Dippel <udippel@gmail.com>]

configure:1575: checking for g++
configure:1604: result: no
configure:1617: checking for C++ compiler version
configure:1620: g++ --version </dev/null >&5
./configure: line 1621: g++: command not found

Therefore, I tried
apt-get install g++
but it gives me
The following packages have unmet dependencies:
  g++: Depends: cpp (>= 4:4.3.2-2) but it is not going to be installed
       Depends: gcc (>= 4:4.3.2-2) but it is not going to be installed
       Depends: g++-4.3 (>= 4.3.2-1) but it is not going to be installed
       Depends: gcc-4.3 (>= 4.3.2-1) but it is not going to be installed
E: Broken packages

What can I do?
