I'm not sure when it started, but on everything more complicated

than print 'Hello World' my perl is failing.

For example:

$ perl -e 'use DateTime;'                            
Attempt to reload List/Util.pm aborted.

Compilation failed in require at /usr/share/perl5/vendor_perl/namespace/autoclean.pm line 11.

BEGIN failed--compilation aborted at /usr/share/perl5/vendor_perl/namespace/autoclean.pm line 11.

Compilation failed in require at /usr/lib64/perl5/vendor_perl/DateTime.pm line 9.

BEGIN failed--compilation aborted at /usr/lib64/perl5/vendor_perl/DateTime.pm line 9.

Compilation failed in require at -e line 1.

BEGIN failed--compilation aborted at -e line 1.

or

$ cpan

Attempt to reload Scalar/Util.pm aborted.

Compilation failed in require at /usr/share/perl5/Safe.pm line 4.

BEGIN failed--compilation aborted at /usr/share/perl5/Safe.pm line 4.

Compilation failed in require at /usr/share/perl5/vendor_perl/CPAN.pm line 57.

BEGIN failed--compilation aborted at /usr/share/perl5/vendor_perl/CPAN.pm line 57.

Compilation failed in require at /usr/share/perl5/vendor_perl/App/Cpan.pm line 290.

BEGIN failed--compilation aborted at /usr/share/perl5/vendor_perl/App/Cpan.pm line 290.

Compilation failed in require at /usr/bin/cpan line 7.

BEGIN failed--compilation aborted at /usr/bin/cpan line 7.

Since I last saw it working, all I can do is remember

upgrading to F35, or the daily updates.

Can anyone suggest where to start?

For example... Why is it trying to reload Scalar::Util?
