I'm trying to get Perl's Finance::Quote module working after MacOS upgrade to 11.4. One of the dependencies is B::Keywords. B::Keywords installation fails a test with this error:
> sudo cpan B::Keywords
[...]
Can't open /System/Library/Perl/5.30/darwin-thread-multi-2level/CORE/keywords.h: No such file or directory at t/11keywords.t line 25
Digging around, I see that keywords.h exists on my system in this location:
/System/Volumes/Data/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Perl/5.30/darwin-thread-multi-2level/CORE/keywords.h
Is there a way to tell cpan (or cpanm, or some other installation tool) where to look for these headers? Or, any other approach to get this working would be welcome.
It seems like they removed the keywords.h from the CORE directory (relative to the path given from $Config{archlibexp}) for the system perl on macOS 10.14, see this bug report.
The reason you are not able to install B::Keywords is due to a failed test 11keywords.t see line 24. Some possible solutions:
sudo cpan -T B::Keywords)
