I have now successfully built and installed the latest 21.1 from CVS after specifying --datadir to configure, so the problem seems to be 21.2-specific. Martin, do you have any comment? - vin acs> I routinely build XEmacs here at work on SunOS-4.1.4 and acs> SunOS-5.5 in order to make sure no major breakage occurs between acs> releases.
