Hi Vincent,

Thanks for your report.

I disagree somehow on the severity, since this is just a warning, when
libxml-libxml-perl uses an older libxml2 runtime than XML::LibXML was
compiled against (which looks correct as you seem to have
2.9.1+dfsg1-3 installed, whereas the recent upload was build against
the version in unstable).

But since the symbols file guards us already against incompatibilities
I think we should just patch away this test in the Debian shipped
module.

(the other possibility would be to build in a mechanism in the package
build to have stricter dependencies only to the version it was built
against, but as long libxml2 is newer than 2.7.4 this is actually fine
in the current case).

Regards,
Salvatore
