lintpkgsrc reports unknown packages

[Riccardo Mottola <riccardo.mottola%libero.it@localhost>]

Hi,

I updated whole userland and then pkgsrc using pkg_rolling-replace. I
had some hiccups so I resumed a couple of times, at the end I got no errors.
Some packages where missing, which I remember to have had, I id "make
install" for them.

I also did run "pkg_admin rebuild"

then I did run "lintpkgsrc -i" to check the result.

Unknown package: 'clang' version 10.0.1nb3
Unknown package: 'ghostscript-agpl' version 9.53.3
Unknown package: 'giflib' version 5.2.1nb4
Unknown package: 'harfbuzz' version 2.7.4
Unknown package: 'libtheora' version 1.1.1nb2
Unknown package: 'libuuid' version 2.32.1
Unknown package: 'libxslt' version 1.1.34nb4
Unknown package: 'nghttp2' version 1.43.0
Version mismatch: 'py-cElementTree' 3.7.10 vs 3.8.8
Version mismatch: 'py-expat' 2.7.18 vs 3.8.8
Version mismatch: 'py-expat' 3.7.10 vs 3.8.8

what are those? packages installed which have no correspondent new version?

I am sure I have clang, it built as a dependency and took several hours!

disc# pkg_info | grep clang
clang-10.0.1nb3     C language family frontend for LLVM
disc# pkg_info | grep harbuzz
disc# pkg_info | grep ghostscript
ghostscript-fonts-8.11nb3 Postscript fonts for Aladdin Ghostscript
ghostscript-agpl-9.53.3 Postscript interpreter
ghostscript-9.05nb24 Meta-package for installing the preferred
ghostscript version
disc# pkg_info | grep giflib
giflib-5.2.1nb4     GIF image format library

So clang is there, with exaclty that version. Harfbuzz is not registered
instead? ghostcript and giflib also are installed.
A mix of issues, how to fix and get out of them?

And why did I get into this strange hole..
