ソースから入れればいいじゃんとか思ったりします。
例えば下記のような手間が減りますし、オプションとか変更しての再インストールが楽になった気がします。
$ rm -i aclocal.m4 $ autoreconf -ifv
stripもしています。
$ file /tmp/event-1.7.2/modules/event.so /tmp/event-1.7.2/modules/event.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, not stripped $ file /usr/lib64/php5.4/lib/extensions/no-debug-non-zts-20100525/event.so /usr/lib64/php5.4/lib/extensions/no-debug-non-zts-20100525/event.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped
このように手動で入れるより便利になっている気がします。
もしくはxstowなどでも良いかと思います。
自分用であれば多少いい加減でも問題ないと思います。
