[Mod_gzip] apache 2.0.40 and error

[darren]

trying to get mod_gzip working. i'm running redhat 8 with apache 2.0.40. i 
had to get apxs rpm from redhat first and then the mod_gzip for apache 2. 
it all seems to compile ok but when i try to restart my server i get:

Syntax error on line 183 of /etc/httpd/conf/httpd.conf:
Can't locate API module structure `mod_gzip_module' in file 
/etc/httpd/modules/mod_gzip.so: /usr/lib/libapr.so.0: undefined symbol: 
mod_gzip_module

line 183 in httpd.conf is:
LoadModule mod_gzip_module modules/mod_gzip.so

i tried looking through the achieves but nothing like this could i see.
