error: libcurl >= 7.28.0 library and headers are required with support for https

I'm sorry for having written such a long question, but given how many times similar questions have been asked, I felt like I had to give a lot more context. ---- In my system, I get. . .

checking for curl-config... /usr/bin/curl-config
checking libcurl version ... 8.2.1
checking curl/curl.h usability... yes
checking curl/curl.h presence... yes
checking for curl/curl.h... yes
checking if libcurl is version 7 and >= 7.28.0... 
configure: error: libcurl >= 7.28.0 library and headers are required with support for https

when trying to install R (**version 4.0.3**, this is non-negotiable) with ./configure --prefix=/opt/R/ --exec-prefix=/opt/R/ --with-libpth-prefix=/opt/ --without-recommended-packages --with-pcre1 --enable-R-shlib. In config.log, I see the following.

And then, after the contents of confdefs.h have been exposed, I see:

There are multiple questions concerning the same error across multiple websites, but none of the solutions I tried worked for me. Since apparently I have multiple versions of available. . .

. . . (I have many more of each), my last tries have revolved around trying to downgrade and/or remove curl and libcurl, but no luck:

(The output continues). I'm working in a docker container, so the above is easily reproducible. I leave the Docker file at the end of this question. I presume the following is useful system information.
