Thanks for all your help. My sysadm is busy with other things, and he 
would not like to install these beta-stuffs. :(

As a sysadm, he must consider far more than just running one command, 
right? At least if I were a sysadm, I'll suspect whether there will be 
side-effects to the existing system. :) There are more than 2,000 
people in my department, and the sysadm didn't know me until I proposed 
him to install perl5.002. He doesn't know me well enough to trust me. :)

Thanks a lot. I tried, but there're still problems. This time it is
libwww-perl-5b10. I wrote a short script trying to access a webpage, of
course, according to libwww-perl cookbook. There's no problem with this
line in my script: 

    $ua->agent('libwww/5b10');

But when it came to the next line:

    $ua->proxy(['ftp', 'gopher', 'http'], "$proxy");

It complained:

    Can't locate auto/LWP/UserAgent/proxy.al in @INC at ./tt line 40

There's indeed no such a dir named "UserAgent", just a file 
"UserAgent.pm". I looked through this file, and found that the subroutine 
"agent" locates before an "__END__", and "proxy" locates after that. I 
supposed this is the reason why perl5.002 can't locate "proxy", so I used 
"#" to mark off this "__END__". Then it got through. No more errors about 
the proxy. Though there're other similar "Can't locate" errors in 
URI::URL or somewhere. My question is, what does "__END__" mean? I 
believe it is not an error by the author. There must be some way to avoid 
this "__END__" automatically, right?
