Hi,
From the error message it seems to me that XML:Parser.pm and/or Parser:Expat.pm were not installed properly (or at least not installed under a default location, somewhere under '@INC').
I am guessing you have the following files/directories under /root/netapp/sdk50/perl/NetApp/XML
Parser.pm # file
Parser # directory
And under Parser directory, you would have the Expat.pm.
Parser directory would also have other dependencies (e.g. Encodings) required for Expat.pm.
If this is the case, you would need to add /root/netapp/sdk50/perl/NetApp/XML/Parser and subsequent dependent directories to the lib path (using "use lib").
However, it is recommended to install the module under usual @INC paths so that "use lib" does not get too big.
Moreover, just ensure that XML:Parser module is "installed" (using make) and not just "copied" under /root/netapp/sdk50/perl/NetApp/XML.
Regards,
Sen.
