gb.highlight and gb.eval.highlight misbehavior in apps and libraries

[Brian G <brian@xxxxxxxxxxxxxxxx>]

I have been updating all my scripts and libraries, apps, to 3.22 version 
and have had an issue with old libraries using gb.eval.highlight with 
apps that I have updated to gb.highlight, some using the 'sh' highlight.

Suddenly when I added that new component replacing gb.eval.highlight, 
apps started crashing saying that 'sh' was not found.... libraries where 
wrong! It looked like the library highlight component was overriding the 
App component... umm.

Is there someway for the runtime/compiler to check that compatible 
versions of components are used between libraries and Apps. I understand 
this is transitory, but somewhat unpredictable. Or maybe I am not 
configuring the app lib usage correctly. I am using the 'use' directive.

When old memory systems like me are involved thing are forgotten, 
perhaps checked during the compile phase of the app.

Anyway it is annoying to have working apps crash, and take some time to 
figure out why..

On the plus side, able to fix up libraries, found lots of missed 
behaviors using the two pass compiler. And some stupid variable reuse in 
loop errors too.
been a lot of fun.. :-(
