Thanks for the examination and the bug report.

Why only in one build? Due to different locale settings? Anyway, if
there's a way that Embperl::Syntax::POD is installed as
/usr/share/man/de/man3/Embperl::Syntax::PO.3pm.gz, that's clearly a
bug and deserves a higher severity than just wishlist.

Sorry, but that's wrong:

→ dpkg -L libembperl-perl | egrep man/de/man./
/usr/share/man/de/man3/Embperl::Features.3pm.gz
→ man /usr/share/man/de/man3/Embperl::Features.3pm.gz

That's clearly my mother tongue. :-)

I disagree at least with the reasoning here.

I nevertheless think, that if Embperl::Features.3pm is the only German
man page in the source package, we can remove it from the binary
package without much impact since that's the kind of documentation you
usually read _before_ installing the package, e.g. online on the
upstream website.

I currently fail to see why this can catch Embperl::Syntax::POD in one
build, but not in another. IMHO this should happen with every build.
Will investigate.
