[CLAM] Failure to build CLAM on Gentoo Linux

[Pau Arumi]

The easiest thing is to go one without using xerces but libxml. See the 
scons options doing scons --help :
scons xmlbackend=xmlpp

If you want to investigate further on the problem, I'd start checking 
that you have libxerces-c.so at paths: -L/usr/local/lib -L/opt/lib
However, this "collect2: ld returned 1 exit status" error you got is not 
the typical error about not finding a library, but I'm not sure.

Please keep us informed on your progress, it would be greate to add 
gentoo specific comments in the INSTALL file or wiki.
