CentOS - Dec 2009 - How do I link to custom libs without affecting system libs (LD_LIBRARY_PATH)

Hi, i am getting an issue with rtorrent that is related to my curl libaries.
 
In summary it requires a later curl libary than CentOS 5.4 uses for its system
files (CentOS uses curl libs version 7.15.5, rtorrent requires 7.19.2 or
greater).
 
To get around this I would like to download the latest curl version and compile
and link to rtorrent without affecting system files.

How can i statically link the latest Curl libs to my rtorrent build? I belive
its to do with LD_LIBRARY_PATH but i am not sure howto proceed:

wget http://curl.haxx.se/download/curl-7.19.7.tar.gz
cd curl-7.19.7./configuremakemake install

The above make install would overwrite or upgrade the existing curl, worried
about breaking existing system!

Many thanks in advance,

no, static linking has NOTHING to do with LD_LIBRARY_PATH.   actually, 
you don't even need a static link here, just link it against the 
alternate libcurl.so that you put in an alternate path.  for instance, 
build your new curl library to live somewhere like /usr/locall/curl/lib, 
then specify this as a -L argument to the link of your rtorrent, which 
likely is built to install to /usr/local/bin or such.

depending on how rtorrent's build works, this could be a simple argument 
to the ../configure, like --path-libcurl=/usr/local/curl/lib
