Error: Multilib version problems found. This often means that the root
cause is something else and multilib version checking is just
pointing out that there is a problem. Eg.:
1. You have an upgrade for libstdc++ which is missing some
dependency that another package requires. Yum is trying to
solve this by installing an older version of libstdc++ of the
different architecture. If you exclude the bad architecture
yum will tell you what the root cause is (which package
requires what). You can try redoing the upgrade with
--exclude libstdc++.otherarch ... this should give you an error
message showing the root cause of the problem.
2. You have multiple architectures of libstdc++ installed, but
yum can only see an upgrade for one of those arcitectures.
If you don't want/need both architectures anymore then you
can remove the one with the missing update and everything
will work.
3. You have duplicate versions of libstdc++ installed already.
You can use "yum check" to get yum show these errors.
...you can also use --setopt=protected_multilib=false to remove
this checking, however this is almost never the correct thing to
do as something else is very likely to go wrong (often causing
much more problems).

Is this ok [y/N]:
Meu amigo não quer remover o nodejs, porque ainda está sendo usado.
Existe alguma solução sobre como instalar hhvm sem remover nodejs instalado.
Nota: Este parece ser um sistema CentOS6, não o CentOS 5.6. Você parece ter versões do gcc (e pacotes relacionados) instaladas que são mais recentes do que as que estão nos repositórios do CentOS6. Além disso, você tem o repositório 'rpmforge', que não é mais recomendado .
Depois de desativar o rpmforge, tente executar yum downgrade gcc . Você deve ter algo como a versão 4.4.7-17.el6.
