You may misunderstand. Only packages that - have compiled code (ie arch: any, and a src/ directory) - use .C() and .Fortran() - actually use the up until recently optional registration - have been built with R (<< 3.4.0) have issues. My detailed write up goes through this. In othre words what you describe may be a complete non-issue. Dirk, traveling -- http://dirk.eddelbuettel.com | @eddelbuettel | e...@debian.org
