This seems to be a portability issue.

cwd()."\n" eq `pwd -L`

I'd say file a bugreport against Cwd and in the meantime resort to `pwd` or `pwd -L` on systems where it fails.

update

after further investigation, it seems that `pwd` inside Perl doesn't default like pwd in bash ... which is unexpected

lanx@ubuntu14-large:/tmp/sym$ perl -MCwd -E'say `pwd` '
/tmp/dir

lanx@ubuntu14-large:/tmp/sym$ pwd
/tmp/sym
lanx@ubuntu14-large:/tmp/sym$ perl -MCwd -E'say `pwd -L` '
/tmp/sym

lanx@ubuntu14-large:/tmp/sym$

so strictly speaking, this is not a bug in Cwd, since cwd() returns the same like `pwd` (which does not always -L )

The question is why is bash's pwd defaulting differently inside Perl?
