Problems building CVS libbonobo with jhbuild

Hello,

I am trying to build libbonobo from CVS using jhbuild.  I am running
into the following error, which I have no idea how to fix:

make[2]: Entering directory `/misc/gnome/build/libbonobo/activation-server'
bison -y -d -v ./activation-context-query-parser.y
rm -f y.output
touch stamp-parser
test -f y.tab.h && mv -f y.tab.h activation-context-query-parser.h || touch activation-context-query-parser.h
flex -t ./activation-context-query-lexer.l >activation-context-query-lexer.c
test -f y.tab.c && mv -f y.tab.c activation-context-query-parser.c || touch activation-context-query-parser.c
make[2]: *** No rule to make target `Bonobo_CosNaming_NamingContext.server', needed by `all'.  Stop.
make[2]: Leaving directory `/misc/gnome/build/libbonobo/activation-server'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/misc/gnome/build/libbonobo'
make: *** [all] Error 2
*** error during stage build of libbonobo: could not build module *** [9/90]

Any help or advice would be appreciated.

Thanks,

Keith.
