regex not found ????

Hi all, I have decided to install squid.1.1.b9 at home (linux 2.1.5) and
it came out with this message :
mulder:~/cache/squid-1.1.beta9/src# make all
gcc -o squid -g acl.o async_io.o background.o cache_cf.o client_db.o

-lbsd
/usr/i486-linux/bin/ld: cannot open -lregex: No such file or directory
make: *** [squid] Error 1

I did a find / -name "*regex*" -print and it came out with :

What could it be ?
(OK the libregex.a is missing, but why squid1.0 compiles ok ?)
Where can I get this regex ?
