I am a bit befuddled about installing XML::LibXML (RHEL6.4, Perl 5.10.1). Our sysadmin seemed to have installed via yum "perl-libxml-perl". However, when I try to run a script I get compile error.

Can't locate XML/LibXML/Reader.pm in @INC (@INC contains: /usr/local/l
+ib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/s
+hare/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /home/
+steps/script/sap/act/test_new_xml_reader.pl line 4.
BEGIN failed--compilation aborted at /home/steps/script/sap/act/test_n
+ew_xml_reader.pl line 4.

Moreover, when we look at cpan, it seems that XML::LibXML was not installed. When we tried to install it, it bailed out pretty quickly.
My questions:

1. What is wrong here? Are they the same module?
2. What should I do to get beyond this? The test is failing, but it doesn't make sense... I verified that /etc/xml/catalog does exist on the system and its content looks ok(?)
