-Q8A- Is there anywhere I can find help with the details of getting Tcl to work on my machine?

From: -VIII- Questions on building Tcl and friends on your system

A8A. Glad you asked!  Look in the Tcl distribution for the file called
"porting.notes".  This will contain a collection of notes that various people
have provided about porting Tcl to various machines and operating systems.
There are also a file called "README" which should be read FIRST - before
doing anything else with the code (this should always be one's first
step with any package).  Finally, there is a "changes" file which details
what has changed since the last release - be sure to read this to see
what might need to change in your programs.
