Atlas library on Caelinux 2010

Hello, I'm trying to recompile the atlas library on caelinux 2010.

I noticed that atlas library provided is single-core and not optimized for multicore processors such as intel corei7.

So I tried the following commands :

apt-get source atlas
cd atlas-3.6.0
fakeroot debian/rules custom

the last command fails and hangs this way :
dh_testdir
make killall arch=foo.choi-laptop
make[1]: entrant dans le répertoire « /home/choi/Soft/atlas-3.6.0 »
make -f Make.top killall arch=foo.choi-laptop
make[2]: entrant dans le répertoire « /home/choi/Soft/atlas-3.6.0 »
make[2]: quittant le répertoire « /home/choi/Soft/atlas-3.6.0 »
make[1]: quittant le répertoire « /home/choi/Soft/atlas-3.6.0 »
chmod +x debian/config.expect
set -e; ARCH_DIR=foo.choi-laptop CACHE_SIZE= BIT=2 DEFAULTS=y \
TDNCOMP=y debian/config.expect | \
awk '/DETECTED!/ {gsub(":","");a=tolower($1);\
gsub("3dnow1","3dnow",a);\
gsub("3dnow2","3dnow",a);\
gsub("sse1","sse",a);\
exit} \
END {if (a=="") a="base"; \
printf("MY_ISA = %s\n",a);\
}' >debian/isa.choi-laptop.d


any clues ?
