Arch linux: Cannot install R package "ragg"

After 10+ years using debian-based linux, I am now using Arch. I use R for data science analysis and development. I am facing difficulties to install the R package ragg (r-ragg), which is a dependency for other libraries I use. When I try to install "ragg" from within R using the install.packages("ragg") command, I get the following error: make: * [/usr/lib64/R/etc/Makeconf:204: agg/src/agg_font_freetype.o] Error 1 which leads to a compilation failure for "ragg". I got the same error message in Arch and in an arch-based OS Any suggestion to resolve this? (I have search a lot how to solve this, without concrete success.) I also tried to install it via terminal using yay -S r-ragg and I received this as feedback:

make: *** [/usr/lib64/R/etc/Makeconf:204: agg/src/agg_font_freetype.o] Error 1
ERROR: compilation failed for package ‘ragg’

==> ERROR: A failure occurred in build().
Aborting...
-> error making: r-ragg-exit status 4
-> Failed to install the following packages. Manual intervention is required:
r-ragg - exit status 4

The relevant part of the Makeconf file is:

$ awk 'NR>200 && NR $@
.cpp.d:
	@echo "making $@ from $ install.packages("ragg")

----- **ISSUE RESOLVED** install.packages("ragg") downloads and installs (or fails to install, in my case) ragg version 1.3.2 from CRAN. This was not working on my workstation running arch-based Endeavour OS. I found the source code for ragg version 1.3.2.9000 at https://r-lib.r-universe.dev/ragg\ and it worked like a charm. No compilation needed, instant success. I loaded the library and ran a test code and it produced the expected output. Case closed. Many thanks for your support through this!
