error /usr/local/share/bison/m4sugar/m4sugar.m4': No such file or directory

[Meir Yanovich]

Hello all
i install bison locally on my account on sun sparc 9
and compile it  successfully but when i run the command :  (example)
bison -y  -d -v `test -f 'soapcpp2_yacc.y' || echo './'`soapcpp2_yacc.y
im getting the error:
bison: cannot open file `/usr/local/share/bison/m4sugar/m4sugar.m4':
No such file or directory
why does bison looking there ? i installed and added to the $PATH the
bin/lib/share directory's
Thanks for the help
