NSLU2 Openslug Firmware - Monit compile problem.

Hi,
i'm trying to compile the lastset version of monit
([url]http://www.tildeslash.com/monit/dist/[/url]) on nslu2 linksys
([url]http://www.nslu2-linux.org[/url]) using OpenSlug
([url]http://www.slug-firmware.net/s-dls.php[/url]) 3.10

Configure command is ok:
------------------------------------------------------------------------------
monit has been configured with the following options:
Architecture: LINUX
SSL support: disabled
resource monitoring: enabled
resource code: sysdep_LINUX.c
Compiler flags: -g -O2 -Wall -D _REENTRANT
Linker flags: -lpthread -lcrypt -lresolv -lnsl
pid file location: /var/run
------------------------------------------------------------------------------

But when i try to make command:

root@nslug_test:~/monit# make
bison -y -dt p.y
make: *** [y.tab.c] Broken pipe
root@nslug_test:~/monit#

Any idea ?
Thanks
