Can we use legacysupport with R packages?

Trying to build vroom package fails on 10.5.8:

* installing *source* package ‘vroom’ ...
** package ‘vroom’ successfully unpacked and MD5 sums checked
** using staged installation
** libs

However legacysupport PG has this definition. Can we set it to be used with R packages?

There is a .r/Makevars file for you to define additional build settings like CFLAGS and LDFLAGS. Maybe try putting stuff in there? Or would it need R to be compiled with legacysupport first?

Thank you.

The ticket can be closed, it works now.
