Problem compiling gnucash 1.6.6

[Jacob Lambrecht]

Hello all, 
I recently grabbed the latest gnucash (version 1.6.6) and I am having
problems compiling it. The configure script runs fine and says that I
meet all requirements (btw, running on Slackware 8.1) but, when I run
"make" I get this error message: 

FLAVOR=gnome guile -c \ 
          "(set! %load-path (cons \"/usr/share/guile\" %load-path)) \ 
           (primitive-load \"./gnc.gwp\") \ 
           (gw:generate-module \"gnc\")" 
ERROR: Unbound variable: gw:new-module 

and the compile stops. I am not to familiar with guile but to me it
looks like guile is not properly loading g-wrap because it is not
finding gw:new-module to be defined. I grabbed the latest g-wrap
(version 1.3.2) and it installed fine with prefix=/usr. I tried to run
make again for gnucash but I got the same error. Can anyone help me with
this please?
