Subject: Readline extension doesn't compile with ruby-1.8.4 on RedHat 7.3

Hi,

I am basically following this guide:

http://hivelogic.com/articles/2005/12/01/ruby_rails_lighttpd_mysql_tiger

and do

curl -O ftp://ftp.gnu.org/gnu/readline/readline-5.1.tar.gz
tar xzvf readline-5.1.tar.gz
cd readline-5.1
./configure --prefix=/usr/local
make
make install

fine. Then

curl -O ftp://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.4.tar.gz
tar xzvf ruby-1.8.4.tar.gz
cd ruby-1.8.4
./configure --prefix=/usr/local --with-readline-dir=/usr/local
make
make install

fine too. I don't get any errors. But

$ ls -w 20 /usr/local/lib/ruby/1.8/i686-linux/*.so
bigdecimal.so*
dbm.so*
digest.so*
dl.so*
enumerator.so*
eruby.so*
etc.so*
fcntl.so*
iconv.so*
nkf.so*
openssl.so*
pty.so*
sdbm.so*
socket.so*
stringio.so*
strscan.so*
syck.so*
syslog.so*
tcltklib.so*
tkutil.so*
zlib.so*

No readline.so in there. What am I doing wrong?

Here is the part of the output where it says it compiles, but it actually 
doesn't:
