Macports tree cleanup

[CHENG Gao]

I think macports tree needs cleanup. For example, there are new/tin
(1.8.1), news/tin-devel (1.7.10) and news/tin-current (1.9.2). In fact
the latest stable release is 1.8.3 and current release is 1.9.2, so
devel version 1.7.10 is obviously outdated and useless.

Another example is apple-gcc. Tree has apple-gcc33 build 1819, and
apple-gcc40 build 5363, while latest Tiger 10.4.10 has build 5367.
Should they be updated? Or even apple-gcc33 be removed?

I trust there are other packages like this.
