For the record---to compile drawterm (http://code.google.com/p/drawterm/) with CONF=osx-x11 on x86_64 (in my case running 10.8.5), just add the required substitution to the makefile:
Make.osx-x11 20 - arch=`uname -m|sed 's/i.86/386/;s/Power Macintosh/power/'`; \ 20 + arch=`uname -m|sed 's/i.86/386/;s/Power Macintosh/power/;s/x86_64/amd64/'`; \ For the moment, I prefer this to drawterm-cocoa because there is no flicker, and window borders remain intact when reshaping with B1 or B2. Mark.
