guile 1.4 and guile 1.(from CVS) in same system

[Ariel Rios]

I have guile 1.4 installed on /usr/ and guile from CVS
under /usr/local/.

I want to compile guile-gtk with CVS guile.

I get:
 address@hidden guile-gtk]$ make
/bin/sh ./libtool --mode=link gcc  -g -O2  -o guile-gtk-1.2
-export-dynamic main.o libguilegtk-1.2.la -L/usr/local/lib -lguile -lm
-L/usr/lib -L/usr/X11R6/lib -lgtk -lgdk -rdynamic -lgmodule -lgthread
-lglib -lpthread -ldl -lXi -lXext -lX11 -lm -lm 
gcc -g -O2 -o .libs/guile-gtk-1.2 main.o .libs/libguilegtk-1.2.so
-L/usr/lib -L/usr/X11R6/lib -lgtk -lgdk -lgmodule -lgthread -lglib
-lpthread -ldl -lXi -lXext -lX11 -lm -lm -L/usr/local/lib -lguile -lm
-L/usr/lib -L/usr/X11R6/lib -lgtk -lgdk -rdynamic -lgmodule -lgthread
-lglib -lpthread -ldl -lXi -lXext -lX11 -lm -lm -Wl,--export-dynamic
-Wl,--rpath -Wl,/usr/local/lib
.libs/libguilegtk-1.2.so: undefined reference to `scm_tc16_fport'
collect2: ld returned 1 exit status
make: *** [guile-gtk-1.2] Error 1
address@hidden guile-gtk]$ 

DoI have to pass specific flags to configure to avoid the problem?
Am i doing something stupid?
