>Description:
When I try to upgrade my installed packages from pkgin I receive these error messages:

```
$ sudo pkgin update
reading local summary...
processing local summary...
processing remote summary (http://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/i386/8.2/All)...

$ sudo pkgin upgrade

1 package to upgrade:
  perl-5.32.1

0 to refresh, 1 to upgrade, 0 to install

pkg_install error log can be found in /var/db/pkgin/pkg_install-err.log
```

Problem listed in log is:
---Dec 13 16:36:11: upgrading perl-5.32.1...
pkg_add: Warning: package `perl-5.32.1' was built for a platform:
pkg_add: NetBSD/i386 8.0 (pkg) vs. NetBSD/i386 8.2 (this host)
pkg_add: Can't open +CONTENTS of depending package p5-Socket6-0.29
pkg_add: 1 package addition failed

Cause of the problem is a wrong compressed tarball:
$ file /var/db/pkgin/cache/p5-Socket6-0.29nb2.tgz
/var/db/pkgin/cache/p5-Socket6-0.29nb2.tgz: XZ compressed data

It's compressed by xz and should be by gzip.

>How-To-Repeat:
Run the following commands on a NetBSD/i386 8.2 host:

1. Put this repository into /usr/pkg/etc/pkgin/repositories.conf:
   http://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/$arch/$osrelease/All

2. Refresh local and remote package lists:
   sudo pkgin update

3. Try to install or upgrade p5-Socket6:
   ( cd /var/db/pkgin/cache && sudo pkg_add ./p5-Socket6-0.29nb2 ) # install
   ( cd /var/db/pkgin/cache && sudo pkg_add -U ./p5-Socket6-0.29nb2 ) # upgrade

>Fix:
Decompress /var/db/pkgin/cache/p5-Socket6-0.29nb2.tgz by xz and compress it with gzip:

cp /var/db/pkgin/cache/p5-Socket6-0.29nb2.tgz /tmp/p5-Socket6-0.29nb2.txz
xz -d < /tmp/p5-Socket6-0.29nb2.txz | gzip > /tmp/p5-Socket6-0.29nb2.tgz

Put /tmp/p5-Socket6-0.29nb2.tgz into the repository and regenerate pkg_summary.
