"Often go to bed with problem and wake up with solution"

I know the feeling :) This isn't intended to be a criticism, but based on following a few of your threads, you seem to be making life unnecessarily difficult for yourself at times. I don't know the exact constraints of your setup, however check out local::lib, cpanm and local::lib would let you install & maintain modules from cpan to a local directory, while being quick and easy to use.

Thanks for suggestion

I took a peek

My solution took 10 minutes and was a one time shot

There is always a workaround for everything. Just have to find it

I will keep the suggestion at hand in case I run into more similar problems

Best regards

To amplify what marto is saying I must point out your solution did not take 10 minutes. It took all the time you sank into it yesterday and the write up and so on; every time you encounter a similar problem, you'll have a similar hurdle. It will also leave code that will be confusing and frustrating for any developer who tries to work on it after you. And that includes you if you come back to it in a year and can't remember what you were thinking. Adopting a community standard solution is going to be easier and better than hacking around a problem almost every time.

Glad that worked for you. The suggestion I made shouldn't take more than 10 minutes to implement, if you base your actions upon the documentation, but I take your point. The advantage of my suggestion would come into play if you had to install/update modules (and their dependencies), the automatic way is much less effort/error prone than doing it by hand.
