Thanks every one.
My os is fedora 4
In fact, I did not know how to install perl before you explained to me, so I just installed LPW(using perl -MCPAN -e 'install "LWP"', not other components.
and now I knew I should install all these missing perl components, and including crap clan-5.3, I thought.
BTW, do you think my MyConfig.pm is right or not?
