===Wrong XML::LibXML Version===

This affects mainly Ubuntu and older Debian distributions where the libxml package is too old. The package installer doesn't check the XML::LibXML version. Either install XML::LibXML 1.63 from cpan or disable it by setting enable_libxml to 0 in <code>perl_lib/EPrints/SystemSettings.pm</code>.

Installing 1.63 from cpan (as root):

 # cpan XML::LibXML

Without either XML::LibXML or XML::GDOME, EPrints uses a bundled XML::DOM implementation that has much lower performance and poorer Unicode support.  In future versions of EPrints only XML::LibXML will be supported.  As this is widely available across the most commonly used Linux operating systems.

Note that you can build Debian packages from CPAN modules using [http://packages.debian.org/dh-make-perl dh-make-perl] in order to keep track of those modules you've been building by yourself. Provided you've already configured your CPAN environment (that is, at least your proxies and servers), you can survive with:

 dh-make-perl --install --notest --cpan XML::LibXML
