How can I get rid of "Best". It is not installed:

root@grizzly:/root(77)# qlist -Iv Best

It was anytime installed as a dependency of an other g-cpan package, but 'equery d' does not show this depency:

 root@grizzly:/root(78)# equery d Best
 * These packages depend on Best:


There is no g-cpan option to deinstall packages:

root@grizzly:/root(80)# g-cpan -h
Usage : g-cpan <Switch(es)> Module Name(s)

--generate,-g
    Generate ebuilds only (Requires working overlays)

--install,-i
    Try to generate ebuild for the given module name
    and, if successful, emerge it. Important : installation
    requires exact CPAN Module Name.

--list,-l
    This command generates a list of the Perl modules and ebuilds
    handled by g-cpan.

--log,-L
    Log the output of g-cpan.

--search,-s
    Search CPAN for the given expression (similar to
    the "m /EXPR/" from the CPAN Shell). Searches are
    case insensitive.

--upgrade,-u
    Try to list and upgrade all Perl modules managed by g-cpan.
    It generate up-to-date ebuilds, then emerge then.

--verbose,-v
    Enable (some) verbose output.

--cpan_reload
    Reload the CPAN index

Portage related options

--ask,-a
    Ask before installing

--buildpkg,-b
    Tells  emerge to build binary packages for all ebuilds processed
    in addition to actually merging the packages.

--buildpkgonly,-B
    Creates  binary packages for all ebuilds processed without actu-
    ally merging the packages.

--pretend,-p
    Pretend (show actions, but don't emerge). This still generates
    new ebuilds.

I tried to remove all Best related files:

root@grizzly:/root(84)# rm /mnt/test3/var_grizzly/cache/edb/dep/var/lib/cpan/perl-gcpan/Best-0.14 /mnt/test3/var_grizzly/log/portage/elog/perl-gcpan:Best-* /usr/portage_grizzly/distfiles/Best-* /mnt/test3/var_grizzly/cache/edb/dep/var/lib/cpan/perl-gcpan/Best* /mnt/test3/var_grizzly/log/portage/elog/perl-gcpan:Best* /usr/portage_grizzly/distfiles/Best-0.14.tar.gz  /var/log/portage/elog/perl-gcpan:Best-* 

Often this is not enough to avoid, that the next 'g-cpan -u' still tries again to emerge "Best". Is there not a better way to get rid of g-cpan installed package.

Hello,

You can use perl-experimental overlay (https://github.com/gentoo-perl/perl-experimental)
$ layman -a perl-experimental
This overlay contain this module (and more)

Also you can try fixed version of g-cpan (https://github.com/bor/g-cpan)
Ebuild you can find here
 https://github.com/bor/gentoo-overlay/tree/master/app-portage/g-cpan
and report how it works (would be very grateful)
for me it works fine

[Comment 2 Sergiy Borodych 2015-01-05 20:32:53 UTC]

The last versions (>0.16.5) should not be affected. Please test it.

I just tried 'g-cpan -u', it fails with:

Could you please provide more information.

$ qlist -Iv app-portage/g-cpan
$ g-cpan -l
$ g-cpan -uvp > log.txt 2>&1

and attach log.txt.
