A compilação do código-fonte do Apache Web Server é sempre divertida.
É muito raro que o Apache seja compilado na primeira execução em um novo servidor.
O fato é que requer muitos pré-requisitos e, se algum deles estiver ausente ou for compatível com a versão, talvez seja necessário gastar muito tempo corrigindo-os.
Eu estava trabalhando no novo servidor Linux 6.4 para instalar o Apache 2.4.6 e encontrei o seguinte erro.

Se você estiver recebendo um erro semelhante, poderá corrigi-lo como eu fiz seguindo.
Solução
Depois de examinar vários parâmetros, notei que isso acontece quando você tem uma versão apr-util inferior a 1.4.1
- Verifique sua versão do apr-util. Se você encontrar uma versão inferior, deverá instalar a versão 1.4.1 ou superior
- Baixe o código-fonte apr-util de http://mirror.nus.edu.sg/apache/apr/
- Extraia o arquivo baixado
Compile e instale da seguinte forma
./configure make make install
Por padrão, ele será instalado em /usr/local/apr/bin/apu-1-config
Agora você pode compilar o apache com o apr-util recém-instalado e tudo ficará bem.
./configure --with-apr-util=/usr/local/apr/bin/apu-1-config
Me ajudou e espero que você também.
