pkg: Skipping unsupported mtree line

[Ross]

Hello

When I install a package almost every time I see a lot of these lines:
...
pkg: Skipping unsupported mtree line: Can't open share/nls/zh_CN.GB18030
pkg: Skipping unsupported mtree line: Can't open share/nls/zh_CN.GB2312
pkg: Skipping unsupported mtree line: Can't open share/nls/zh_CN.GBK
pkg: Skipping unsupported mtree line: Can't open share/nls/zh_CN.UTF-8
pkg: Skipping unsupported mtree line: Can't open share/nls/zh_CN.eucCN
pkg: Skipping unsupported mtree line: Can't open share/nls/zh_HK.Big5HKSCS
pkg: Skipping unsupported mtree line: Can't open share/nls/zh_HK.UTF-8
pkg: Skipping unsupported mtree line: Can't open share/nls/zh_TW.Big5
pkg: Skipping unsupported mtree line: Can't open share/nls/zh_TW.UTF-8
pkg: Skipping unsupported mtree line: Can't open share/pixmaps
pkg: Skipping unsupported mtree line: Can't open share/sgml
pkg: Skipping unsupported mtree line: Can't open share/skel
pkg: Skipping unsupported mtree line: Can't open share/xml
pkg: Skipping unsupported mtree line: Can't open tests
pkg: Skipping unsupported mtree line: Can't open www
...
And so on. This is usually about share/locale/*, share/nls/* and man/*
files.

Do I have a problem? Everything seems to be working OK.
