How to compile libcURLpp

Hi,
I just ran into problems with compiling libcurlpp
This happened on a clean installation

[root@localhost curlpp-0.5.2]# make
make all-recursive
make[1]: Entering directory `/root/Desktop/curlpp/curlpp-0.5.2'
Making all in curlpp
make[2]: Entering directory `/root/Desktop/curlpp/curlpp-0.5.2/curlpp'
if /bin/sh ../libtool --silent --tag=CXX --mode=compile g++ -DHAVE_CONFIG_H -I. -I. -I.. -I../ -g -W -Wall -Werror -I/usr/local/include -MT CurlHandle.lo -MD -MP -MF ".deps/CurlHandle.Tpo" -c -o CurlHandle.lo CurlHandle.cpp; \
then mv -f ".deps/CurlHandle.Tpo" ".deps/CurlHandle.Plo"; else rm -f ".deps/CurlHandle.Tpo"; exit 1; fi
cc1plus: warnings being treated as errors
OptionBase.hpp:39: warning: 'class cURLpp::OptionBase' has virtual functions but non-virtual destructor
make[2]: *** [CurlHandle.lo] Error 1
make[2]: Leaving directory `/root/Desktop/curlpp/curlpp-0.5.2/curlpp'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/root/Desktop/curlpp/curlpp-0.5.2'
