should libapt-pkg-perl go t-p-u?
libapt-pkg-perl spends after 2days, but IMHO it won't enter to Sarge.
New libapt-pkg-perl is built on sid, but perl is freezed component,
and perl-base has version incompatibility between Sarge / Sid.
i386, alpha, mipsel are built with same perl-base version of Sarge
(5.8.4-2.2), but m68k and others look new perl-base 5.8.4-2.3.
I think you should ask RM how to resolve it. (maybe you need to upload
alternative version of libapt-pkg-perl to testing-proposed-updates.)
