才发现MacPorts 默认会重新安装已过期（outdated）的package。初衷是好的，只是很多大软件dependent的小软件包实在没有更新的必要，反而浪费很多时间－－－纯个人感觉。
现在装qt4-mac，遇到的更新有：
Deactivating openssl @0.9.8l_0+darwin
---> Computing dependencies for openssl
---> Installing openssl @0.9.8n_0+darwin
---> Activating openssl @0.9.8n_0+darwin
Deactivating sqlite3 @3.6.16_0
---> Computing dependencies for sqlite3
---> Installing sqlite3 @3.6.23.1_0
---> Activating sqlite3 @3.6.23.1_0
Deactivating jpeg @6b_3
---> Computing dependencies for jpeg
---> Installing jpeg @8a_0
---> Activating jpeg @8a_0
Deactivating tiff @3.8.2_3+macosx
---> Computing dependencies for tiff
---> Installing tiff @3.9.2_3+macosx
---> Activating tiff @3.9.2_3+macosx
还有个dbus，不知是干什么的。有段注释备忘一下

昨天装xine-lib (1.1.16.1_1)遇到的更新更多，不过没记下来，也不重要
