3. Do I need Tcl/Tk in order to build Perl/Tk?
Short answer: No not at all. Perl/Tk is completely independent of Tcl/Tk.
Longer answer: In order to build Perl/Tk from source code you do need a recent version of perl, the perl/Tk source code kit, a graphical user interface library such as Xlib, Presentation Manager, or Win32; a C or C++ compiler, and a make utility. In some rare cases Perl/Tk binaries are distributed for some platforms but that is more the exception than a general rule (see below).
If you will be attempting to port Perl/Tk to your platfrom then you might want to consult the document at: http://w4.lns.cornell.edu/~pvhp/ptk/ptkPORT.html
where each of these components is discussed in a bit more detail (with an emphasis on Xlib).

3. 编译安装Perl/Tk是否需要Tcl/Tk？
简短的回答：完全不用！因为Perl/Tk是完全不依赖Tcl/Tk的。
更具体的回答：如果要从源代码来编译安装Perl/Tk，你需要1）较新版本的Perl；2）Perl/Tk源代码包；3）图形用户界面库，例如Xlib，显示管理器（Presentation Manager）或者Win32；4）C或C++的编译器；5）make工具。偶尔，Perl/Tk也会发布针对一些系统平台的二进制版本。
如果你确实想在你的系统上安装Perl/Tk，那么你可以参考下面的这个文档：

这里对上面提到各个条件都做了更加详细的讨论（重点是Xlib）。
