error getting working directory

[ParityError]

If you're in a directory that no longer exists and attempt to run any commands relating to MacPorts you'll get an error:

$ cd ~/desktop $ mkdir test $ cd $_ $ rm -rf ../test $ port search xorg-server 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 5725)

Yes, it's a strange to remove a directory that you are pwd, but maybe MacPorts should have some type of check in that circumstance?
