Help with APACHE 2.0 connector

[amayawen]

Redhat Linux 7.2
Apache 2.0.39
I'm building the apache-tomcat connector mod_jk.
I downloaded jakarta-tomcat-connectors-4.0.4-src.tar.gz from the tomcat website.
I'm working in the directory jakarta-tomcat-connectors-4.0.4-src/jk/native/apache-2.0
Before running the build-unix.sh, I changed the APACHE_HOME to /usr/local/apache2, which
is where I installed apache 2.0.39.
Then I ran the build-unix.sh
Compile is ok. But there's an errow while linking:

/usr/lib/gcc-lib/i386-redhat-linux/2.96/../../../crt1.o: In function `_start':
/usr/lib/gcc-lib/i386-redhat-linux/2.96/../../../crt1.o(.text+0x18): undefined r
eference to `main'
mod_jk.o: In function `ws_start_response':
/usr/local/apps/jakarta-tomcat-connectors-4.0.4-src/jk/native/apache-2.0/mod_jk.
c:225: undefined reference to `apr_psprintf'
.... a lot of errors

I can't find any mod_jk binary for apache 2.0
Can anyone know what's wrong with this?
