CreatePackageReport() fails with errors about loading some compiled libraries

[jameslamb]

I'm unsure of the exact issue, but the following code

pkg_name <- YOUR_PACKAGE_NAME
CreatePackageReport(
    pkg_name
    , report_path = file.path(getwd(), "report.html")
)

Yields an error like the following on the Function Network tab (generated by FunctionReporter):

## Error in dyn.load(file, DLLpath = DLLpath, ...): unable to load shared object '/Library/Frameworks/R.framework/Versions/3.5/Resources/library/gdtools/libs/gdtools.so':
##   dlopen(/Library/Frameworks/R.framework/Versions/3.5/Resources/library/gdtools/libs/gdtools.so, 6): Library not loaded: /opt/X11/lib/libcairo.2.dylib
##   Referenced from: /Library/Frameworks/R.framework/Versions/3.5/Resources/library/gdtools/libs/gdtools.so
##   Reason: image not found

I saw this error for the following:

• gdtools
• ggiraph

The error is slightly longer when running for RGtk2, but I think it's the same root cause

## Error in dyn.load(file, DLLpath = DLLpath, ...) : 
##   unable to load shared object '/Library/Frameworks/R.framework/Versions/3.5/Resources/library/RGtk2/libs/RGtk2.so':

## Please install GTK+ from http://r.research.att.com/libs/GTK_2.24.17-X11.pkg
## If the package still does not load, please ensure that GTK+ is installed and that it is on your PATH environment variable
## IN ANY CASE, RESTART R BEFORE TRYING TO LOAD THE PACKAGE AGAIN
