1.Mac Port中第三方软件下载包存放的默认路径是：/opt/local/var/macports/distfiles/
为了提高安装速度，可以在安装新port时直接将此目录下的文件拷贝到新的Mac Port相同的目录中就可以避免Port去网上下载。

2.使用Mac Port前应该首先更新Port的index
输入: $ sudo port -v selfupdate (强烈推荐第一次运行的时候使用-v参数，显示详细的更新过程)

3.查看Mac Port中当前可用的软件包及其版本输入: $ port list

4.查看有更新的软件以及版本输入: $ port outdated

5.升级可以更新的软件输入: $ sudo port upgrade outdated

6.在Mac Port搜索需要安装的软件包输入: $ port search maven

        HuiMinmatoMacBook-Pro:Downloads zikercn$ port search maven
       
        maven @1.0.2 (java, devel)
       
        stub port, use maven1 instead
       
        maven-ant-tasks @2.1.3 (devel, java)
       
        Use many of Maven's artifact handling features from Ant.
       
        maven1 @1.1 (java, devel)
       
        A java-based build and project management environment.
       
        maven2 @2.2.1 (java, devel)
       
        A java-based build and project management environment.
       
        maven3 @3.0.4 (java, devel)
       
        A java-based build and project management environment.
       
        maven_select @0.3 (sysutils)
       
        common files 

        for 

        selecting default Maven version
       
        Found 6 ports.

7.搜索到需要安装的软件包之后，如何查看具体的软件包的内容和说明
输入: $ port info maven3

        maven3 @3.0.4 (java, devel)
       
        Description:          Maven is a Java project management and project
       
        comprehension tool. Maven is based on the concept of a
       
        project object model (POM) 

        in 

        that all the artifacts
       
        produced by Maven are a result of consulting a well
       
        defined model 

        for 

        your project.Builds, documentation,
       
        source 

        metrics, and 

        source 

        cross-references are all
       
        controlled by your POM. Maven 3 aims to ensure backward
       
        compatibility with Maven 2, improve usability, increase
       
        performance, allow safe embedding, and pave the way to
       
        implement many highly demanded features.

        //maven

        .apache.org/
       
        Build Dependencies:   kaffe
       
        Runtime Dependencies: maven_select

8.查看即将安装的或者已经安装的软件包的依赖关系
输入: $ port deps maven3

Full Name: maven3 @3.0.4_0

Build Dependencies: kaffe

Runtime Dependencies: maven_select

9. 查看安装时允许客户定制的参数输入: $ port variants maven3

1	`maven3 has no variants`

10.查看了软件包的内容和说明,并确认确实要安装,则输入: $ sudo port install maven3

        To 

        make 

        maven 3.0.4 the default, please run
       
        sudo 

        port 

        select 

        --

        set 

        maven maven3
       
        --->  Cleaning maven3
       
        --->  Updating database of binaries: 100.0%

        for 

        linking errors: 100.0%
       
        --->  No broken files found.

11. 卸载已经用Mac Port安装的软件输入: $ sudo port uninstall maven3

---> Deactivating maven3 @3.0.4_0

---> Cleaning maven3

---> Uninstalling maven3 @3.0.4_0

--->  Cleaning maven3

MacPorts卸载删除

1.卸载原有的MacPorts(如果你没有安装,直接跳过这一步,输入: $ port version 查看)
#原版使用MacPorts安装过的软件在/opt/local目录下,删除之前最好查看下,心里有个数.

        sudo 

        port -f uninstall installed
       
        sudo 

        rm 

        -rf  [/加下面的每条]
       
        /opt/local
       
        /Applications/DarwinPorts
       
        /Applications/MacPorts
       
        /Library/LaunchDaemons/org

        .macports.*
       
        /Library/Receipts/DarwinPorts

        *.pkg
       
        /Library/Receipts/MacPorts
