在debian上安装PHP时遇到的问题
配置的时候出现了这样的错误：

checking for Kerberos support... no
checking for pkg-config... /usr/bin/pkg-config
checking for OpenSSL version... >= 0.9.6
checking for CRYPTO_free in -lcrypto... yes

checking for CURL in default path... not found
configure: error: Please reinstall the libcurl distribution -
  easy.h should be in <curl-dir>/include/curl/

然后我在网上找到一个解决办法：
#apt-get install curl
#apt-get install libcurl3
#apt-get install libcurl4-gnutls-dev

但是运行apt-get install libcurl4-gnutls-dev的时候又出现了错误：
# apt-get install libcurl4-gnutls-dev

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
  libcurl4-gnutls-dev: Depends: libcurl3-gnutls (= 7.18.2-8lenny4) but 7.19.5-1.1 is to be installed
  Depends: libgnutls-dev but it is not going to be installed
  Depends: libidn11-dev but it is not going to be installed
  Depends: libkrb5-dev but it is not going to be installed or
  hurd but it is not installable
  Depends: libldap2-dev but it is not going to be installed
E: Broken packages
请问高手们这是怎么回事啊？

------解决方案--------------------
少了这几个包

Depends: libcurl3-gnutls (= 7.18.2-8lenny4) but 7.19.5-1.1 is to be installed
Depends: libgnutls-dev but it is not going to be installed
Depends: libidn11-dev but it is not going to be installed
Depends: libkrb5-dev but it is not going to be installed or
hurd but it is not installable
Depends: libldap2-dev but it is not going to be installed

最好一起apt-get install
------解决方案--------------------
安装程序最好找好他们的依赖包， 在一起安装这样不容易出错
------解决方案--------------------
最好是缺什么装什么，根据错误信息找到要安装的文件，执行 apt-get install 包名

即可
------解决方案--------------------
直接在新立得里面装不就可以了 自己装还要配置php、mysql和apache之间的关联
