dm incompatible with pkgdown in a package that imports dm

[MatthewHeun]

Steps to reproduce:

• Use RStudio to start a new project of type package in an empty folder. I created the empty folder at ~/Desktop/testdmpkgdown/ like this:

• Add the line "Imports: dm" to the DESCRIPTION file

• Install the package (Build|Install Package)

• Type "pkgdown:::build_site_external()" in the console (Or choose "Build pkgdown" from the Addins menu)

Expected result:

• Browser window opens with a (very rudimentary) pkgdown site for the new package

Actual result:

Error: 
! in callr subprocess.
Caused by error in `load_imports(path)`:
! 
ℹ See `$stdout` for standard output.
Type .Last.error to see the more details.

Here is the output from .Last.error:

<callr_error/rlib_error_3_0/rlib_error/error>
Error: 
! in callr subprocess.
Caused by error in `load_imports(path)`:
!

Impact:

• This issue prevents constructing pkgdown documentation websites for packages that Imports: dm.

Workarounds:

• None known at this time.

Additional information:

• All other imported packages that I tried work correctly. For example,
  • "Imports: magrittr" works
  • "Imports: stringi" works
• Any time "dm" is included in the Imports: field, the error occurs.
  • "Imports: magrittr, dm" fails
  • "Imports: stringi, dm" fails

Machine, OS, etc:

• macOS Sonoma 14.1.1
• R 4.3.2
• RStudio 2023.12.1+402
• dm 1.0.10
• pkgdown 2.0.7

Thanks, this is weird.

@dickoa @josesamos: You have packages that import dm. Can you build pkgdown sites for these packages?
