To "use" expected version of .pm file

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

There are 2 versions of perl installed on my machines. How to make sure perl script uses correct/expected .pm file at run time. Generally Perl gets installed with Oracle & same is case with my product.now when we execute perl file it gives error about .pm file Perl lib version (v5.8.3) doesn't match executable version (v5.8.0) at D:\oracle \10.2.0\perl\5.8.3\lib\MSWin32-x86-multi-thread/Config.pm line 32. Compilation failed in require at D:\oracle\10.2.0\perl\5.8.3\lib\MSWin32-x86-mul ti-thread/Errno.pm line 8. I have used strict.pm & other .pm files in the code how to avoid this situation?

perl holds the paths to it's modules in the array @INC. A common way to manipulate that array is to add paths using `use lib '/path/to/module'`. Also you might want to check the environment variable PERL5LIB.	[reply]

i have written following line - use lib "lib path"; but it gives error "unable to find lib.pm" There is no lib.pm file as such. few lines of code are - use strict; use Getopt::Std;	[reply]

Sounds like you have a broken install, as lib.pm is standard since version 5.001. What does `perl -V` report?	[reply] [d/l]

lib is part of Perl, so that's very odd. But you don't have to use lib to modify `@INC`. `BEGIN { unshift @INC, '/home/user/perllib'; }` [download]	[reply] [d/l] [select]
