安装了ptkdb，仍不能调试，请大侠帮忙分析下：
是不是缺少哪个pm文件呢？
E:\study\perl\Devel-ptkdb-1.1071>perl -d:ptkdb test.pl
1..1
bad option "side": must be -after, -anchor, -before, -expand, -fill, -in, -ipadx
, -ipady, -padx, -pady, or -side at C:/Perl/site/lib/Tk/Widget.pm line 1214.
at C:/Perl/lib/Devel/ptkdb.pm line 1143
Can't call method "setup_main_window" on unblessed reference at C:/Perl/lib/Deve
l/ptkdb.pm line 3897.
END failed--call queue aborted at test.pl line 4080.

谢谢！
