#773 check for version of perl-XML-Simple in OSCAR 4.2.1

[Anonymous]

it seems that currently OSCAR 4.2.1 to install
perl-XML-Simple just checks to see if it is installed,
and does not actually check the version. Thus if
installing OSCAR 4.2 on top of a previous version of
OSCAR, the following error appears:
> error: Failed dependencies:
> perl(XML::Simple) >= 2.08 is needed by
> systemimager-server-3.5.3-3oscar.noarch
> $pm->install ($dm->query_required_by ()) failed at
./wizard_prep line 312
