Compile failing CentOS 5.1

[XtremeX]

When I try to compile using either ./Config or

./configure --with-showlistmodes --enable-hub --enable-ssl --enable-ziplinks --enable-inet6 --enable-prefixaq --with-listen=5 --with-dpath=/root/manual install/Unreal/Unreal3.2.7 --with-spath=/root/manual install/Unreal/Unreal3.2.7/src/ircd --with-nick-history=2000 --with-sendq=3000000 --with-bufferpool=18 --with-hostname=ushindi.auswired.com --with-permissions=0600 --with-fd-setsize=1024 --enable-dynamic-linking

I get the following.

I am at a loss, and consider UnrealIrcd the best so am hoping to get this working.
Any Ideas?
