PackageCompiler.jl Portability Issue

I’m having an issue with PackageCompiler.jl, the error I’m getting on the sister PC is:

fatal: error thrown and no exception handler available.
InitError(mod=:Libiconv_jll, error=ErrorException("Artifact "Libiconv" was not installed correctly. Try `using Pkg; Pkg.instantiate()` to re-install all missing resources."))

As can be seen, the complaint is about Libiconv_jll. The issue is this package is not in my manifest! Here is the status from my project:

So where does Libiconv_jll come from?

Additionally, and possibly the real issue, when I update my package using Pkg.update(“AM2App”), this makes a lot of changes to the Manifest.toml file. But, there is a known issue with FFTW, which must be constrained to v1.4.1 (the current version 1.4.3 has a portability issue) and FFTW_jll which must be constrained to v3.3.9+7. I have added a constraint to FFTW so that it remains at v1.4.1, but the FFTW_jll will still update to v3.3.9+8. The format of the version number doesn’t seem to work with the Project.toml [compat] section, so I can’t constrain the FFTW_jll package. Therefore, after the Manifest.toml file updates to v3.3.9+8, I manually copy back the FFTW_jll section to Manifest.toml

[[FFTW_jll]]
deps = ["Artifacts", "JLLWrappers", "Libdl", "Pkg"]
git-tree-sha1 = "5a0d4b6a22a34d17d53543bd124f4b08ed78e8b0"
uuid = "f5851436-0d7a-5f13-b9de-f02708fd171a"
version = "3.3.9+7"

After saving Manifest.toml, I run Pkg.instantiate() and then run PackageCompiler.create_sysimage()

Am I possibly breaking something by doing this? The compiled sys image from PackageCompiler.jl does work fine on my PC, but when I try to use on a sister PC it fails. Note, it did work before I made any changes to the Manifest file, in which case the EzXML → XML2_jll → Libiconv_jll chain was removed from my Manifest because of an update to TimeZones.

Finally, is there anyway to only update the specified package and leave the rest of the Manifest alone? TimeZones is a dependency of a dependency which I certainly did not need to update. In my case I’d like to make the smallest changes to Manifest possible when I update a specific package (i.e. the one I need for my sys image generation).
