I was recently called in to fix a perl problem where a script broke when moved to a new server. In this case, the perl being used turned out to be the version included with Oracle and not that installed with the OS. There were two different versions of perl installed on the same machine with different libraries/versions in each. Once I had them update LWP on the OS version of perl and to use that version of perl and not the version installed with Oracle, the script worked fine again. I just wanted to mention a possibility for you to check.
