What error where you getting? (The actual error messages are usually the most useful when debugging.)

Did you also install the required TT_lib2 files?

You shouldn't have needed to change the RBZ to ZIP. Why not just use Install Extension from Preferences>extensions?

FYI, I'm running SU8 on a Mac running 10.7.5. However, the RBZ problem occurs with all flavors of extensions regardless of their date.

re: RBZ to ZIP
I've tried the Install-Via-Preferences route, but I get problems. I've installed the TT_lib2, but via copying the contents of an unzipp'd RBZ, so perhaps there is a file to be dealt with that was not resolved in the simple copy maneuver?

Here's the error message when running the Preferences Extension Installer:

"Unable to install this Extension
SketchUp was unable to install the Extension you have chosen for some unknown reason.
Consult your Extension's documentation for additional help."

....I know, helpful, right? I ran a couple permission repairs on my Mac, with reboots, that didn't change anything.

re: Unzipping and copying file structure into SU

This is what pops up when starting SU each time:

"Error Loading File core.rb
uninitialized constant TT::System"

I can't wait to use this! Except - I got errors trying to install RBZ files, so I changed ".rbz" to ".zip" and copied the files in. After resolving all of the "Can't find blah.rb" issues, I'm getting one last error:

"Error Loading File core.rb
uninitialized constant TT::System"

Since the Solid Inspector ran on one model, do I just cope with a constant popup error? Any thoughts on this?
