问个有关centos yum 的问题？

权老实

原centos 4.3
现在有4.4的。想 通过yum升级到4.4
问题：
4.3时，删去了原来的mysql php http ，然后是自己重新下载的源代    码，编译的。而4.4中的mysql php http 仍比较自己编译的版本低不想用。
用yum upgrade 能升级到4.4吧？？？
如何能指定一些不用升级的？？？

权老实

yum upgrate
出错
--> Running transaction check
--> Processing Dependency: libmysqlclient.so.14(libmysqlclient_14) for package: dovecot
--> Processing Dependency: libmysqlclient.so.14 for package: dovecot
--> Finished Dependency Resolution
Error: Missing Dependency: libmysqlclient.so.14 is needed by package dovecot
Error: Missing Dependency: libmysqlclient.so.14(libmysqlclient_14) is needed by package dovecot

要是去掉更新dovecot包
则出下面的错：

什么原因？？

权老实

搞定：
1)禁止某些更新
vi /etc/yum.conf
exclude=httpd  
（注意。一定要将你原来删去的rpm包禁掉，否则、、、、这不，我刚刚重新又编译安装的fcitx ,它与更新的输入法又冲啦！）
2)yum remove dovecot
  yum upgrade
就以可以正常更新
应该升级到4.4  （还没发现有什么 正常的）

我的Yum Update也可更新，完事之后我的Fcit被 改了。我又重新改的配置文件。
