解決策

• Download - The Apache Portable Runtime Project から apr-1.4.6.tar.gz、apr-util-1.4.1.tar.gz をダウンロードする。

# cd /usr/local/src/httpd-2.4.2/srclib
# ls apr*
apr-1.4.6.tar.gz  apr-util-1.4.1.tar.gz #←ここにおく
# tar xfvz apr-1.4.6.tar.gz
# tar xfvz apr-util-1.4.1.tar.gz 
# mv apr-1.4.6 apr
# mv apr-util-1.4.1 apr-util
# cd ..
# ./configure --prefix=/usr/local/apache2
