it appears that oracle has gobbled up the paths to the perl library. this happened to me once, and i simply reinstalled perl and all was well.

however, if you don't want to uninstall Perl (understandable), simply set your PERL5LIB environment variable to c:\perl\lib;c:\perl\site\lib.

or, as a third alternative, you could explicitly specify these paths with use lib "C:\\perl\\site\\lib"; and use lib "C:\\perl\\lib"; of course, this isn't too portable.
