I know this topic is probably very old now. But I just got started working on Perl. No matter what I do, I keep getting this error "Can't locate Net/Telnet.pm in @INC (@INC contains: C:/strawberry/perl/lib C:/strawberry/perl/site/lib.) at telnetting.pl line 4." and then I get a compilation error. 1. I tried using the older versions of Net::Telnet. 2. I have put the Net-Telnet-3.0.1 directory in the c:\strawberry\perl\lib folder. Does the backslash-forward slash matter? How do I change the @INC? 3. I changed the name of another directory that was named "Net" to "ABCD" just to get something working. 4. I have tried referencing the whole path to Telnet.pm. This is frustrating. Thank you for your help.
