安装php出错，求教~

下面是我安装php的过程：(My SQL和apache已装)
#tar -jxvf php-4.3.4.tar.bz2

#cd php-4.3.4

./configure --with-mysql=/usr/local/mysql --with-apxs=/usr/local/apache/bin/apxs

#make (过程有warning如下)
......
......
*** Warning: inter-library dependencies are not known to be supported.
*** All declared inter-library dependencies are being dropped.

*** Warning: libtool could not satisfy all declared inter-library
*** dependencies of module libphp4.  Therefore, libtool will create

......
......
Build complete.
(It is safe to ignore warnings about tempnam and tmpnam).

# make install

cp: stat‘libs/libphp4.so’失败: 没有那个文件或目录
apxs:Break: Command failed with rc=1
make: *** [install-sapi] Error 1

请问我该怎么解决这个问题呢？
(我去看过php-4.3.4/libs目录只有libphp4.a,libphp4.la)
apache和php的安装,是参照动态模式装的。

我记得的情形大概是：

编译 apache 时，要指定 php 源代码（已经安装了 php-devel，就不用）的位置。
这样完成后，再编译 php ，就不会有问题。
