Apacheのconfigure時のエラー「configure: error: no acceptable C compiler found in $PATH」の原因と解決方法
Linux（例：CentOS 5）でApacheをソースからインストールするためにconfigureを実行すると、
configure: error: in `/var/tmp/httpd-2.2.17/srclib/apr':
configure: error: no acceptable C compiler found in $PATH
というエラーが出てconfigureに失敗することがある。
《例》
[root@nobuneko local]# cd /var/tmp/httpd-2.2.17
[root@nobuneko httpd-2.2.17]# ./configure --prefix=/usr/local/apache2 --enable-so

See `config.log' for more details.
configure failed for srclib/apr
「no acceptable C compiler found」というエラーメッセージより、Cコンパイラが見つからない、ということが分かるので、yumなどでCコンパイラをインストールする。

これで、Cのコンパイラのインストールが完了。
この後、再度configureを実行すると、エラーにならず、configureに成功した。
