Can't locate object method new via package URI::URL

ybiC has asked for the wisdom of the Perl Monks concerning the following question:

Dear brothers and sisters in Perl,
I'm rewriting an existing codelet that nails up a dial connection via HTTP fetches, so that it randomly selects from a list of web pages to fetch and waits a random length of time between fetches. All fairly straightforward and no problems. That is, until I move the code from my workstation to the dial-connected firewall/proxy, where it fails to run and gives this error:

Can't locate object method "new" via package "URI::URL" at ./wtest.pl line 12

I've reinstalled URI, downgraded it to v1.17, upgraded it back to v1.18, all to no avail. It can't be left to run on my workstation, as it would only fetch from firewall's proxy instead of from the web. What other troubleshooting steps might you recommend?

Minimized code and additional details follow.
stymied, puzzled, baffled and perplexed,
Don

Try adding `use URI::URL;`. And consider using `URI` instead (`URI::URL` is for backwards compatibility with older LWP code).	[reply] [d/l] [select]

See how you only `use LWP::UserAgent;` but then call new methods on to other packages. OK so we have all got used to using HTTP::Request's new() method when we use LWP. But why does this actually work. Afterall we have not a `use HTTP::Request;` -> because LWP::UserAgent did so this module is in %INC. Evidently you have different versions of LWP::UserAgent. A simple `use URI::URL` will fix the problem as Fletch notes. So will syncronising you LWP::UserAgent on the problem box with the one on the OK box. You can have a look at all the modules available to a script in %INC like: `print $_, "\n" for keys %INC;` [download] cheers tachyon s&&rsenoyhcatreve&&&s&n.+t&"$'$`$\"$\&"&ee&&y&srve&&d&&print	[reply] [d/l]
