Ask Google to find you this file (plenty of hits):

wxGTK-2.3.2-1.i386.rpm

Like I said, these are optional example components. (not Boa spesific)
The bcrtl also contains COM components which you certainly don't need ;)

The plug-in under: Plug-ins/UserCompanions.plug-in.py defines the Boa 
wrappers so that these components can be created from the Palette.

Hint: To disable a plug-in, rename the file, I rename them to e.g.:
Plug-ins/UserCompanions.plug-in.disabled.py

Boa itself does not rely on them.

If the preference to installBCRTL is on, the filedates are checked
at startup and updated if needed, but if you aren't editing them,
it will only copy them the first time.

Not currently no, the bcrtl components generate source like this:

from wxPython.lib.bcrtl.user.ExampleST import *

Put it on your path then :)

Dig for what? :)

This is the error I get when I try to build a Boa rpm:

distutils.errors.DistutilsPlatformError: invalid Python installation:
unable to open /usr/lib/python2.2/config/Makefile (No such file or
directory)

Which is completely true, I have binary rpm installation of Python,
but surely you don't need to build you own Python before you can 
build rpm files with distutils!
