Problemas com instalação de PPPoE

Estou tentando fazer o artigo PPPoE + Radius + BandLimit só que ele está dando um monte de erros no meu Conectiva 10.

Eu executo o ./configure do ppp e ele dá esse monte de erros..

Código :

[root@server ppp]# make

E no outro .tar quando executo o ./go

Código :

[root@server rp-pppoe-3.5]# ./go
Running ./configure...
loading cache ./config.cache
checking for gcc... gcc
checking whether the C compiler (gcc  ) works... no
configure: error: installation or configuration problem: C compiler cannot create executables.
Oops!  It looks like ./configure failed.

O que pode ser isso ?
