Problems after hombrew uninstall

Problems after hombrew uninstall

Something went wrong... After searching laboriously, and trying many
things, I've ended up here.
I'm learning, so please bear with me. I was following a tut on updating my
mac to php5.4 things were going well. That was until I had to step away.
Now I don't remember where I left off, and couldn't find the same tut any
more. I did get as far as creating the my_phpinfo.php file. But when I
brought it up it showed 5.3. So... I end up digging, and digging. Then
turning to homebrew. I installed homebrew and had the standard
Consider amending your PATH so that /usr/local/bin is ahead of /usr/bin in
your PATH
I followed this and to no avail, it didn't work. I found the wiki for the
homebrew uninstall and think I'm in worse shape. I tried to reinstall.
After trying to reinstall I get
-bash: curl: command not found
-bash: ruby: command not found
I decided to try to restat Apache...
-bash: sudo: command not found
So now I've stopped, and need HELP!
