Problems building with guile2

[Mike Alexander]

I tried to merge maint into master tonight.  Although the merge seemed 
to be fairly easy, the result wouldn't build.  I tried to figure out 
why, but eventually gave up.  The problem exists in maint too, it won't 
build with guile2.   There were a lot of changes to various Scheme 
files recently on maint and something broke building with guile2.

The first error I get is when it tries to compile 
app-utils/business-prefs.scm.  It fails trying to load 
gncmod-backend-dbi and gncmod-backend-xml and then gives up because 
gnc:module-begin-syntax is unbound.  I have no idea why this file 
should be loading those two backends.  I managed to make it load 
gncmod-backend-xml ok, but nothing I did would make it load 
gncmod-backend-dbi.  As far a I can tell no other Scheme file loads 
this.  I also don't understand why gnc:module-begin-syntax is unbound. 
Even adding an explicit load-module call for gnc-module didn't get it 
bound and that module should already be loaded anyway.

The complete build log is below.  Does anyone have any idea what is 
wrong?
