installation error

[marco]

Hi,
I have a problem to install the program.
when i type the command "make" from /src dir, It display this error:
address@hidden src]# make
rm -f a.*
ALL_CFLAGS=' -Dhas_conf_h  -I. -I. -g -O' \
CC='gcc' \
COMPAT2='0' \
DIFF3='/usr/bin/diff3' DIFF3_BIN='1' \

DIFF_SUCCESS='0' \
DIFF_FAILURE='1' \
DIFF_TROUBLE='2' \
ED='/bin/ed' \
LDFLAGS='' LIBS='' \
RCSPREFIX='/usr/local/bin/' \
SENDMAIL='"/usr/lib/sendmail"' \
/bin/sh -x ./conf.sh 3>&1 >a.h 2>conf.err
./conf.sh: testing permissions ...
./conf.sh: This command should not be run with superuser permissions.
make: *** [conf.h] Error 1

What does it means?
How can I solve i?

Thank you
