Full Discussion: sudo chown -R `whoami` /usr/local

sudo chown -R `whoami` /usr/local
I was following a tutorial on installing Homebrew and I changed the ownership of /usr/local/ to me. Now McAfee Security won't start This is the exact line I typed:

Code:
sudo chown -R `whoami` /usr/local

Then I tried to fix it with:
Code:
sudo chown -R root /usr/local

I still can't start mcafee. It say "McAfee Security software failed to launch. error Code: 1

I'm not sure who the original owner and group were. also in the process of installing Homebrew I changed permissions with
Code:
sudo chmod o-w/usr/local/bin
sudo chmod o-w /usr/local

I Think I changed them back correctly with:
Code:
sudo chmod o+w /user/local  
sudo chmod o+w /usr/local/bin

Does anyone know what I need to do to get Mcafee working again?

Here is what ls -l looks like for those directories
Code:
drwxr-xr-x   2 root  staff    68 Jun 17 10:20 Cellar
drwxr-xr-x   6 root  staff   204 Jun 16 23:58 Library
drwxr-xr-x  10 root  wheel   340 Nov 16  2009 McAfee
-rw-r--r--   1 root  staff  1603 Jun 16 23:58 README.md
drwxrwxrwx  31 root  staff  1054 Jun 16 23:59 bin
drwxr-xr-x   8 root  wheel   272 Sep 23  2010 git
drwxr-xr-x   4 root  wheel   136 Sep 12  2010 hermes
drwxrwxrwx   6 root  wheel   204 May  2 20:57 include
drwxrwxrwx  23 root  wheel   782 May  2 20:57 lib
drwxrwxrwx   4 root  wheel   136 Nov 16  2009 man
drwxrwxr-x   3 root  staff   102 Oct  7  2010 sbin
drwxrwxrwx  10 root  wheel   340 Jun 16 23:58 share

Any advice is welcome

I rebooted and McAfee starts up. I'm hoping that everything is the way it should be. I can't run a manual update, but that may be because its already up to date.
