[R-SIG-Mac] "R CMD build" ...Error... "processing vignette ... failed with diagnostics:, Pandoc is required to build R Markdown vignettes but not available."

[Spencer Graves]

Hello, All:


	  "R CMD build" fails for me, apparently because it cannot find pandoc, 
even though R in a command prompt finds it. This is with R 4.4.0 under 
macOS 14.5. I get the following in a Terminal:


___% R CMD build fda
* checking for file ‘fda/DESCRIPTION’ ... OK
* preparing ‘fda’:
* checking DESCRIPTION meta-information ... OK
* installing the package to build vignettes
* creating vignettes ... ERROR
--- re-building ‘BasisBasics.Rmd’ using rmarkdown
Error: processing vignette 'BasisBasics.Rmd' failed with diagnostics:
Pandoc is required to build R Markdown vignettes but not available. 
Please make sure it is installed.


	  "Pandoc 3.2 already installed", per the following interaction with R 
in said Terminal:
	

 > library(pandoc)
 > pandoc_install()
ℹ Fetching Pandoc releases info from github...
✔ Pandoc 3.2 already installed.
   Use 'force = TRUE' to overwrite.
 >
 >
 > pandoc_is_active()
Error in pandoc_is_active() :
   argument "version" is missing, with no default
 > pandoc_is_active("system")

	  Suggestions?
	  Thanks,
