compilation problem with mod_proxy_html

["sharath reddy" <reddy.web@xxxxxxxxx>]

By compiling of the mod_proxy_html (version 2.5.2) for apache2.0.50(on LINUX) with the command  
"apxs -c -I/usr/include/libxml2 -i mod_proxy_html.c", I get the follow error: 


[root@slsxwebdev1

Can anybody help me to fix this problem.
