I have solved this first problem by including an IMPORT line.  Here's
the entire contents of my cxxtest.jam (critiques welcome, and there may
be typos as I had to fat-finger this in):

rule init ( ) { }

import testing ;

#----------------------------------------------
# Empty rule needed to get 'make' to work
rule gen-cxxtest-runner ( target : sources + : properties * )
{
}

#----------------------------------------------
# Takes a set of one or more cxxtest header files as $(>)
# and creates a C++ source file in $(<)
#
# Still need to provide a way for user to specify the
# desired flags
#
actions gen-cxxtest-runner
{
   cxxtestgen.pl --abort-on-fail --have-eh --have-std --error-printer -o
$(<) $(>)
}

#----------------------------------------------
# Create a test executable but don't run it
#
rule cxxtest-exe ( target-name :
                   cxxtest-headers + :
                   sources * :
                   requirements * :
                   default-build * :
                   usage-requirements * )
{
   exe $(target-name) :
       $(sources) $(target-name)_runner.cpp :
       $(requirements) : $(default-build) : $(usage-requirements) ;

   make $(target-name)_runner.cpp : $(cxxtest-headers) :
gen-cxxtest-runner ;
}

#----------------------------------------------
rule run-cxxtest ( target-name :
                   cxxtest-headers + :
                   sources * :
                   requirements * :
                   #default-build * :
                   #usage-requirements *
                  )
{
   make $(target-name)_runner.cpp : $(cxxtest-headers) :
gen-cxxtest-runner ;

   unit-test $(target-name) :
             $(target-name)_runner.cpp $(sources) :
             $(requirements) ;
}

#----------------------------------------------
