'i am not able to use it even if i add the line in my scripts "use lib <local module path>".'

Did you read Re: problem while installing the perl modules for clearcase?

'I am installing them using their source codes, so whenever i tried to run commmand "make" or "make install" , it gives me error.'

Which modules? What errors occured? Part of the problem with your question and the replies is that you don't tell us enough information to advise. There is no point in telling us 'it gives me error' unless you tell us what 'it' is and what the error was. You could post the command you're using to install a module, along with the output. Read and understand How do I post a question effectively?.
