Cygwin 环境下安装 Gtk2

这里的 Gtk2 是指 Perl 的 Gtk2 模块，Cygwin 环境下通过 CPAN 是无法直接安装的，需要修改了 Makefile.PL 之后手动安装。

这是 Dirk Froemberg 向 Torsten Schoenfeld 提交的 patch，到现在为止还没有被合并进 source。

找来找去，找不到吃掉空间的文件，还是经过好友指点，学到了这个命令：

[root@localhost~]# lsof | grep deleted
logswatch 14767    zimbra    1w      REG        8,7    1830440     384006 /tmp/logswatch.out (deleted)
logswatch 14767    zimbra    2w      REG        8,7    1830440     384006 /tmp/logswatch.out (deleted)
......

意为列出已被删除，但仍被进程占用中的文件。然后就是处理（杀掉？）掉相关进程，释放文件，空间就回来了。
