这个是什么原因啊，can't locate loadble object for module proc::processTable

Can't locate loadble object for module Proc::ProcessTable in
@INC(@inc contains:D:perl2/site/lib .) at security.pl line 32
Compilation failed in require at at security.pl line 32
Begin failed--compilation aborted at security.pl line 32


已经从cpan下载了Proc::ProcessTable modules
不过用ppm工具找不到该modules，是直接下的，然后makefile
不知到是不是这个原因，
要怎么解决啊，
