Estou tentando instalar o ruby, mas quando executo o rbenv install -v 2.2.3 , recebo o seguinte erro:

Eu não sou especialista, mas parece que o gcc pode estar faltando. Eu tento instalar o gcc via sudo apt-get install gcc e recebo o seguinte erro:
Setting up gcc (4:4.8.2-1ubuntu6) ...
update-alternatives: error: alternative path /usr/bin/gcc doesn't exist
dpkg: error processing package gcc (--configure):
subprocess installed post-installation script returned error exit status 2
Errors were encountered while processing:
gcc
E: Sub-process /usr/bin/dpkg returned an error code (1)
Veja o que eu tentei:
sudo apt-get install build-essential
então
sudo dpkg --purge gcc
sudo apt-get clean
sudo apt-get -f install
Mas nada disso funcionou. Eu acho que pode até ser relacionado a permissões, eu tive recentemente que restaurar / var / e tive alguns erros não relacionados de permissões / propriedade desde então. Alguma ideia do que está causando isso?
EDITAR:
Quando executo update-alternatives --query cc , obtenho o seguinte resultado:
update-alternatives: error: no alternatives for cc
Quando eu executo ls -l /usr/bin/{cc,gcc} , aqui está o que eu recebo:
ls: cannot access /usr/bin/cc: No such file or directory
lrwxrwxrwx 1 root root 7 Apr 7 2014 /usr/bin/gcc -> gcc-4.8
A execução de ls -ld /var/lib/dpkg/alternatives/{,cc} me dá:
ls: cannot access /var/lib/dpkg/alternatives/cc: No such file or directory
drwxrwxr-x 2 mre mre 4096 Dec 17 00:06 /var/lib/dpkg/alternatives/
Da execução de sudo apt-get install --reinstall gcc-4.8 gcc , obtive:

Então eu achei esta resposta e funcionou então agora gcc está compilando mas quando eu corro rbenv install -v 2.2.3 eu recebo este :
