今天安装Perl的调试工具， Devel-ptkdb-1.1091.tar.gz解压后make test时报错：Can't locate Tk.pm。
This's because x11/tk doesn't contain Tk.pm. You need to install x11/p5-Tk.
具体怎么做呢？
1）sudo apt-get install libx11-dev
2）sudo cpan -i Tk ##会自动地从CPAN上下载安装Tk.pm
此时还是会报错：make[1]: *** [Xlib_f.o] Error 1
make[1]: Leaving directory `/home/orisun/.cpan/build/Tk-804.029-NXYYkx/pTk'
make: *** [pTk/libpTk.a] Error 2
SREZIC/Tk-804.029.tar.gz
/usr/bin/make -- NOT OK
一切搞定后再安装Devel-ptkdb。
