Bob,

I am not sure if there is a way to change the saved installation directory,
but you should be able to change it each time Mathematica starts by editing
the sysinit.m file.

I have not tested this, but I think this should accomplish what you want.

Right click on Mathematica.app and click "View package contents"
>From there navigate to the folder: SystemFiles/Kernel/SystemResources/
Select the folded relevant to your system.

Open sysinit.m in a text editor (it would be a good idea to make a backup
first)

On a new line just after "Begin[ "System`Private`"]" set the
$installationDirectory variable.
For example:
$InstallationDirectory="/Applications/Wolfram/Mathematica_7.0.1.app"

I hope this helps.   Maybe someone else can offer you a solution which would
seem like less of a "work-around"

Regards,
Nate
