Yeah:

$ perl -e 'eval { use Carp::Always; }'
Can't locate Carp/Always.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at -e line 1.
BEGIN failed--compilation aborted at -e line 1.
$ perl -e 'eval { require Carp::Always; }'
$ echo $?
0
