configure error on compile ports

[rmgls]

Hello list,

Please can you tell me what to do about this error
(elinks but also many other compile)?


:info:configure checking for gcc... /usr/bin/clang
:info:configure checking for C compiler default output file name... 
:info:configure configure: error: C compiler cannot create executables

some details:
osx11.2. new macports (/opt/local entirely deleted first).
gcc and clang correctly seated in /usr/bin and running fine.
xcode up-to-date, and commandline tools installed!

Thanks for your answer.
