Now we are starting again from the beginning...
I asked for this (making tetex* predepend on dpkg-perl) but Ian Jackson
objected since this is too risky (check out debian-devel).
Would you agree with this policy:
Using Perl modules in maintainer scripts
========================================
Maintainer scripts may only use Perl modules which are
included in the perl-base package or any other package marked
Essential. In addition, any Perl modules installed by a package
may be used in _its own_ "postinst" script (but not in any other
maintainer script).
Note, that sometimes it's necessary to include the Perl modules
in the control area of a package (installed in
/var/lib/dpkg/info/package.*) to avoid unnecessary "Conflicts:"
with other packages installing the same modules.
It is not allowed to use modules from a "Depended" or
"Pre-Depended" package in a maintainer script, since this is too
dangerous.
Thanks,
Chris
