so here we have evidence that indeed you have a locally compiled curl version on your system in addition to the Ubuntu one (which would not put anything into /usr/local/lib). So it seems that at some point you have downloaded curl sources and installed them into your system, and that this version (as it has no https support) got in the way configuring R 4.1.0. If you still have the sources lying around, there is an uninstall target in the Makefile, so you should go to the source directory and do a sudo make uninstall to get rid of your local curl version in /usr/local/.
