in thread Confused about Perl module installation
I've seen two common cases that give the symptoms you describe:
Some people will compile a new perl from source manually, or use a tool like perlbrew to automate the process. I use perlbrew because it makes managing multiple versions of perl on my box simple. That way, my development box has all the versions of perl any of the production servers use.
Since production changes have to go through testing and review processes, not all servers always run the same version of perl. So to fix a problem for a particular server, I can tell perlbrew to switch to a particular version, check out the application code and get to work. Or if I want to upgrade perl on a server, I can tell perlbrew to install the new version and run the application through its paces on my dev box to see if there are any problem areas.
When your only tool is a hammer, all problems look like your thumb.
