Recompiling bash to avoid shellshock seems to have messed up bash
Well, wget isn't installed by default on Mavericks. You could install it through homebrew though.

If you installed wget yourself at one time then you may just need to adjust your $PATH to find it again.

PATH=/path/to/wget:"${PATH}"

Take a look in /bin and /usr/bin to see what tools are installed and try one of them to see if Bash is working correctly.
