Package: dselect
Version: 1.8.3
Severity: grave
apt is 0.5.0
dpkg on dselect didn't list the maintainer, so I CC'd this to APT list,
please forward to correct list as needed.
1. I installed latest Debian from net, using the 2r2 boot disks
and pointing apt to unstable sites (below)
2. After selecting packages and installing them, something happened
and Perl was not working well any more. Can't give any more details
on this.
3. After breakage, I was unable to install perl using
dselect due unresolved Perl
dependency problems. I didn't understand why dselect refused to
to install perl 5.5 due to unresolved dependencis. in dselect.
--> It even didn't offer Perl 5.6 to install, only 5.5 was in the
list.
Anyway the dselect went beserk.
4. I downloaded latest perl and built it.
5. Dselect still didn't work, and the reason is that standard Perl
does not include /usr/share/perl5 in @INC
Now, I would consider it improvement for Dseelect if it always called
underlying install scripts with
-I/usr/share/perl5
And not to rely on the currently installed Debian perl configuration.
Even better: every critical script would "source" lib-config.pm,
which included "use lib /PATH/HERE" for critical Perl libraries.
Yes, I solved the problem with dselect by compiling the
/usr/share/perl5 into Perl's @INC, but how many novices
know and cope with this?

The submitter has never replied to this, and it's clear that the errors
reported are the result of trying to use a broken locally installed Perl
with Debian packages. This is not a dselect bug (should have been dpkg,
really), since it is absolutely not dpkg's job to fiddle with Perl
include paths: that will break in the future if and when Perl's include
path is changed, and furthermore dpkg is not even generally in a
position to be able to control the options passed to perl.
The perl problems reported in 2.2r2 should have been fixed long since.
Our perl packages have gone through a number of substantial revisions
since then.
