[CLAM] Failure to build CLAM on Gentoo Linux

[David García Garzón]

The configure test that checks your system having XercesC++ library properly installed is failing. It finds the headers and the library but not the proper library version. It may be a XercesC++ version conflict. Compiler seems to find 2.7 headers but a different version for the library. Did you installed XercesC++ in a local directory? Could you give the list more details on how did you installed XercesC++? Check link names and so-names (links on the /lib directory) related to xerces.

If problems with XercesC++ persist, try to change the xmlbackend to 
libxml++. But if you have a vanilla Gentoo install we are interested on identify any problem that could affect to other Gentoo users.

David.
