The warning appears in
/usr/lib/x86_64-linux-gnu/perl5/5.20/XML/LibXML.pm
#-------------------------------------------------------------------------#
# test exact version (up to patch-level) #
#-------------------------------------------------------------------------#
{
my ($runtime_version) = LIBXML_RUNTIME_VERSION() =~ /^(\d+)/;
if ( $runtime_version < LIBXML_VERSION ) {
warn "Warning: XML::LibXML compiled against libxml2 ".LIBXML_VERSION.
", but runtime libxml2 is older $runtime_version\n";
}
}
Either the exact version is needed, in which case a versioned
dependency is missing, or the exact version is not needed and the
warning is useless and would introduce more problems than trying
to solve hypothetical ones: in interactive use, such warnings are
annoying and distracting, and in a context where stderr is checked,
it can break things (in cron scripts, this would spam the user).
