Package Fails to Compile From Source on Windows

[ArcadeAntics]

When I try to install 'curl' from source, it comes with the following error which claims that it cannot find function 'download.file'. I have my 'Rscript' set so that only base is attached upon starting a new R session (that is, RSCRIPT_DEFAULT_PACKAGES=NULL). This could be fixed by changing 'download.file' to 'utils::download.file' (and same with 'unzip', change to 'utils::unzip'). Thank you!
