Compiling under OS X 10.4 got an error

[Russ Urquhart <russurquhart1 comcast net>]

Hi,

I had previously compiled 4.6.0 under an earlier version of OS X  
without any probs.

I got the following when i tried to compile 4.6.1 under Tiger:

Making all in slang
if gcc -DHAVE_CONFIG_H -I. -I. -I..  -I./include -I../intl -I../intl   
-I/usr/local/include/glib-1.2 -I/usr/local/lib/glib/include - 
D_INTL_REDIRECT_MACROS -MT slsmg.o -MD -MP -MF ".deps/slsmg.Tpo" -c - 
o slsmg.o slsmg.c; \
then mv -f ".deps/slsmg.Tpo" ".deps/slsmg.Po"; else rm -f ".deps/ 
slsmg.Tpo"; exit 1; fi
slsmg.c:76: error: `SLtt_Has_Alt_Charset' undeclared here (not in a  
function)
slsmg.c:78: error: `SLtt_Use_Blink_For_ACS' undeclared here (not in a  
function)
make[2]: *** [slsmg.o] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2


Can anyone help or shed some light on this?

Thanks

Russ
