求救：calibre在ubuntu下安装后启动报错！

系统为ubuntu10.04，calibre从2009、2010、2011，已经试过好几个版本，报错基本都是“Can't find a usable tk.tcl in the following directories”
报错如下所示

---------------------------------------------------------------------------------------------------------------------------------

This probably means that tk wasn't installed properly.
