This is an auto-filed bug because dev-lang/perl calls cc directly. The issue was originally discovered on amd64, but it may be reproducible on other arches as well. If you think that a different summary clarifies the issue better, feel free to change it. Attached build log and emerge --info. NOTE: If you think it doesn't make sense fix these type of issues, I'd like to point out that won't be possible use a different CC implementation (like clang) by setting the CC variable. So this issue has been reproduced by setting the CC variable to x86_64-pc-linux-gnu-gcc and by removing the /usr/bin/cc - /usr/bin/gcc binaries.

Important context from QA report: ./hints/linux.sh: line 174: gcc: command not found Configure: line 6387: nm: command not found Configure: line 22940: cpp: command not found While these aren't fatal for perl's build, like ar, they're likely to lead to bad consequences.

For now, this: > ./hints/linux.sh: line 174: gcc: command not found Seems like a red herring, but the code involved is a bit of a nightmare: https://metacpan.org/source/SHAY/perl-5.30.2/hints/linux.sh#L166-206 This could *potentially* mess up plibpth computation, and possibly libquadmath support. The rest are addressed.
This is now in 5.32.1
I wonder if Kent made a mistake at https://github.com/Perl/perl5/issues/17791#issuecomment-630145202. We don't ever really care about LD, it's deprecated to use it as a path to the actual linker. --ld=$(tc-getCC) seems to work for me so far in some brief testing (Module::Install doesn't respect CCLD), and we already do 'export CCLD=$(tc-getCC)' and 'unset LD' in perl-module.eclass.

Calling LD directly at all is deprecated and people should do it via the compiler driver, hence set LD="$(tc-getCC)". Note that we already unset LD anyway since 6eb964b504c3aef2192403cbf383ae75d46990ff.
