Bug#469044: libphp-serialization-perl: specifies DH compat version 6 but depends only on version 5

[Andreas Ferber]

Version: 0.27-1

Hi,

when backporting the package to etch for myself, I noticed that the
package specifies a debhelper compat version (in debian/compat) of "6",
however it Build-Depends only on debhelper version 5 upwards.
