Ivan is undoubtedly more knowledgeable on these matters than I, but I 
noticed that you are trying to install the current version of RQuantLib 
into a library that appears associated with a significantly older 
version of R than is current the current version. (And I second the 
advice that this is a question properly addressed to the R_SIG-mac 
mailing list but only with a much better description of version of your 
setup and how R was installed. You might want to install RQuantLib for a 
time frame that matched R 4.1.x. The archive is here:


You may also want to set the compile flags so that R can find your 
version of gfortran. That can be done within install.packages but most 
experts would prefer that you do it from a system terminal session with 
$ R CMD INSTALL. You can find details at the r help page `
