All packages does already have to be corrected in order to follow the
new perl policy. This is a one-time change. You won't have to do it
more than one time.

That's not enough for a binary perl module. Furthermore using PREFIX can
have some strange results when used in conjunction with complete path
given to INSTALL*DIR.

The recommended way of doing is described in the perl policy. You really
can't do it wrong if you're paying attention to what you do.

Using the prefix only is NOT enough. Otherwise do you really think we
would have used explicit INSTALLMAN1DIR for ages ?

This is from debian-policy ...

The perl policy is not a law. You respect it or not. You do whatever
you want with your packages ...

Somewhere in the ExtUtils module. I don't know exactly where but I ran
into trouble one day because of this.

If you set only INSTALLPRIVLIB without setting INSTALLARCHLIB on the
command line, the resulting INSTALLARCHLIB will be
$INSTALLPRIVLIB/$arch-linux ...

Concerning changing Config.pm, Darren will do whatever he thinks
it's the best. It really doesn't matter as the official way of building
perl module is to explicitely specify where things get installed. This
way you /always/ know what happens.

BTW, with the FHS beeing officially adopted, one day I'll have to change
the INSTALLMANXDIR to point to /usr/share/man/manX ...
