Permissions issues after updating

I'm receiving the following errors after logging back in after running barracuda up-stable:

-bash: /bin/uname: Permission denied
-bash: [: =: unary operator expected
-bash: /bin/sed: Permission denied
-bash: /bin/ls: Permission denied
-bash: /bin/uname: Permission denied
-bash: [: =: unary operator expected
-bash: /bin/sed: Permission denied
-bash: /bin/ls: Permission denied

This a separate, non-Barracuda (i.e. not o1.ftp) account I set up for admin. I'm not sure what other details might be helpful. If there's anything else I can provide, let me know.
