This is not accurate.  At least one of the reference implementations of 
libraries and macros, at

   http://www.het.brown.edu/people/andre/macros/index.html

runs as is in both the MzScheme and the Petite Chez interpreters' REPLs, using 
only the ability of these implementations to interpret vanilla r5rs code.  It 
is straightforward to port (and prior versions have been ported) to other 
vanilla r5rs Scheme systems.  All that is needed to completely integrate 
with these interpreters is to plug a call to the above expander at the 
appropriate native slot between the R and E of the REPL.
