You can do this in dict_appl.inc
...
.include "words/set-current.asm" ; for marker
.include "words/set-order.asm"   ; ./.

Then build a new amforth, which can load marker.
There may be better solutions ...

I'm using avra 1.2.2 Build 94 (11. May 2007) (from 
avra_1.2.2-1_i386.deb) for my stuff.

However, there are some files with version 2 assembler 
around, e.g. those directly out of Atmels AVRStudio files, 
which avra cannot handle correctly. This may be another 
source of problems.

Always worth a try, but no garantees ;-)
I'm mostly working with atmega32 not atmega169 as on the 
butterfly.

Good luck!
