OK so I have instead (outside of the virtualhost tags):
-initial-env RT_INSTANCE_PATH=/home/testguy

I am using /home/USERNAME for all of my separate instances. Using this, 
I get a 500 internal server error from the webpage, and the following in 
the apache error log:

Mine are a little different but I believe the problem is earlier than 
the script aliases.

See the above. I am 99% certain the patch was applied properly. I 
checked out the modified files (RT.pm, webmux.pl, rt-setup-database) and 
the installed files all appear to have the correct contents as far as 
the patch goes. The problem appears to be that something is not grabbing 
the environment variables properly, but I'm not sure how to proceed from
