经过各位的提醒和搜索，终于将 Zend Optimizer 2.5.10 装好，现整理如下：

我的 uname -a :


CODE:[Copy to clipboard]FreeBSD fb60.abc.org 6.0-RELEASE FreeBSD 6.0-RELEASE #0: Thu Nov  3 09:36:13 UTC 2005     root@x64.samsco.home:/usr/obj/usr/src/sys/GENERIC  i386
根据 “FreeBSD扫盲之apache＋php＋ZendOptimizer简单安装、设置 ” 一文 ，用ports 装ZendOptimizer，apache2+mod_php4 已装好。


CODE:[Copy to clipboard]另外安装ZendOptimizer也最好用ports安装，不过我是习惯了直接装了，呵呵，ports安装的话方法是：
下载ZendOptimizer-2.5.10a-freebsd5.1-i386.tar.gz后，置于/usr/ports/distfiles目录下，
cd /usr/ports/devel/ZendOptimizer
make install clean;
我的安装完后 phpinfo() 只显示：


CODE:[Copy to clipboard]This program makes use of the Zend Scripting Language Engine:
Zend Engine v1.3.0, Copyright (c) 1998-2004 Zend Technologies
没有

说明我的 Zend 只是 1.3.0 版，而不是版主令人羡慕的 Zend Optimizer v2.5.10, ！

接上文（用 ports 安装未果）：

将手动下载的 /usr/ports/distfile/ZendOptimizer-2.5.10a-freebsd5.1-i386.tar.gz 拷贝到 /tmp：


CODE:[Copy to clipboard]#tar -xzf ZendOptimizer-2.5.10a-freebsd5.1-i386.tar.gz

#cd ZendOptimizer-2.5.10a-freebsd5.1-i386

#./install.sh
提示：


CODE:[Copy to clipboard]/usr/libexec/ld-elf.so.1: Shared object “libcrypt.so.2″ not found, required by “php”
于是：


CODE:[Copy to clipboard]fb60# find / -name “libcrypt.so”
/usr/lib/libcrypt.so
接着：


CODE:[Copy to clipboard]ln -s /usr/lib/libcrypt.so /usr/lib/libcrypt.so.2
接着安装，又提示：


CODE:[Copy to clipboard]fb60# ./install.sh
/usr/libexec/ld-elf.so.1: Shared object “libm.so.3″ not found, required by “php”
接着找、做连接：


CODE:[Copy to clipboard]fb60# find / -name “libm.so”
/usr/lib/libm.so
^C
fb60# ln -s /usr/lib/libm.so /usr/lib/libm.so.3
再安装，又提示：


CODE:[Copy to clipboard]fb60# ./install.sh
/usr/libexec/ld-elf.so.1: Shared object “libc.so.5″ not found, required by “php”
做连接：


CODE:[Copy to clipboard]fb60# ln -s /usr/lib/libc.so /usr/lib/libc.so.5
再安装，ok了。下面的根据提示进行即可。
