Milter-greylist

I had a free moment, so I thought I'd try the dev version 2.1.5, but  
recieved the following error:

/usr/local/src/milter-greylist-2.1.5# make
gcc -g -O2 -Wall -D_BSD_SOURCE -c milter-greylist.c
gcc -g -O2 -Wall -D_BSD_SOURCE -c pending.c
gcc -g -O2 -Wall -D_BSD_SOURCE -c sync.c
bison -y -p`echo conf_yacc.c|sed 's/^\([^_]\{1,\}_\).*$/\1/'`  
conf_yacc.y

*** Error code 1
