Qual pacote instalar?

Fui instalar o lMule 1.3.1, e deu o seguinte erro:

[root@starfleet lmule-1.3.1]# ./configure
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking for g++... g++
checking for C++ compiler default output... configure: error: C++ compiler cannot create executables
See `config.log' for more details.
[root@starfleet lmule-1.3.1]#

Qual é o Compilador do C++, eu já instalei o GCC.
