 Sorry for the awkward summary. This demonstrates what I mean:

 {{{
 % mkdir foo
 % cd foo
 % (cd .. && rmdir foo)
 % cd $(port dir subversion)
 shell-init: error retrieving current directory: getcwd: cannot access
 parent directories: No such file or directory
 error getting working directory name: no such file or directory
     while executing
 "pwd"
     invoked from within
 "set current_portdir [pwd]"
     (file "/opt/local/bin/port" line 4857)
 %
 }}}
 This error only makes sense when invoking port(1) without specifying a
 port, since it looks for a Portfile in the current working directory.

 I assume the same behavior would be observed with the -D option.
