[BUG] "Could not load library" Error and Suspected Julia Installation Breakage

[TheCedarPrince]

Per a small discussion on the Julia Slack, I am opening an issue to track a strange error. For this issue the following specs are used:

OS: macOS Catalina 10.15.7 Julia Version: Julia 1.7.0 Package Compiler Version: v2.0.5

Additionally, here is what I have in my global Julia environment if there is any interference being caused by them in this issue:

(@v1.7) pkg> st
      Status `~/.julia/environments/v1.7/Project.toml`
  [6e4b80f9] BenchmarkTools v1.3.1
  [35a29f4d] DocumenterTools v0.1.13
  [634d3b9d] DrWatson v2.9.1
  [5fb14364] OhMyREPL v0.5.12
  [9b87118b] PackageCompiler v2.0.5
  [14b8a8f1] PkgTemplates v0.7.26
  [295af30f] Revise v3.3.3
  [0c614874] TerminalPager v0.3.0

What I do exactly to create this issue is the following steps:

1. Create clean and empty environment
2. Execute using PackageCompiler
3. Execute ]activate .
4. Add the following package ]add https://github.com/TheCedarPrince/JMentalHealthEquity#finalize-baseline
5. Run create_sysimage(["MentalHealthEquity"]; sysimage_path = test.so")

Which leads to the following error:

julia> create_sysimage(["MentalHealthEquity"]; sysimage_path = "test.so")

It seems like something may have broken in my Julia install somewhere while working with PackageCompiler. After suspecting my installation was broken based on #424 , I installed Julia 1.7.2. The compilation now works successfully and as expected.

@KristofferC , you said this wasn't really PackageCompiler's fault. I am curious as to what you think may have happened here. Thanks!

[KristofferC]

I really doubt this could have broken your julia installation since this shouldn't touch any julia files. Does that reproduce for you?

After having used Julia 1.7.2 to create a few system images, I am not running into this issue anymore. Sadly, when I tried to installed 1.7.2 it removed my 1.7.0 installation and after looking at the Julia Downloads release page, I cannot find where to reinstall 1.7.0. So, this may have "just" been a strange fluke but at this time, I am unable to reproduce my original error. If you want to, feel free to close this @KristofferC or I can provide more details perhaps for posterity if others run into this same strange behavior. Thanks!
