Dear Prof. Ripley,

Thanks a lot for your reply!

Thank you, that is good to know. It could be interesting to learn from the
fixes of these R packages, do you maybe have a list of the package names
already which you could share?

Packages should aim to be platform-independent. So rather than expect

Fully agree, generally we aim to be compatible with all CRAN tested
systems. In particular for Mac I am quite new to the different combinations
of R itself and packages being compiled, which compiler versions can be
combined etc.

Thanks, I will also test the 'development' toolchain and see what happens.

It is possible to download different CLTs from

Thank you, that is very helpful!

Thank you, that is very helpful!
