Why can't I modify the contents of this folder when I'm part of the group with full permissions?

dsmith@ip-xx-xxx-xxx-xx:~$ groups dsmith
dsmith sudo py
dsmith@ip-xx-xxx-xxx-xx:~$ sudo chmod -R g+rwxt /usr/local/virtualenvs
dsmith@ip-xx-xxx-xxx-xx:~$ ls -al /usr/local

    You'll need to have read (well, execute at least) on all parent directories, and write access to the file in question.

    Also, groups dsmith shows what groups the dsmith user is in; while groups shows what groups the current user is in. You'll need to log in anew if they show different output.

    Another thing to check is SELinux; it might be interfering.
