Building Xerces-C++ 3.0.1 on Mac OS X was/is a breeze. Given below are the steps that I've followed.
1) Downloaded xerces-c++ 3.0.1 source from http://xerces.apache.org/xerces-c/download.cgi
2) Extracted the zip-file into a convenient folder (obvious :-))
3) Spent few minutes reading http://xerces.apache.org/xerces-c/build-3.html
4) Ran "./configure CFLAGS="-arch x86_64" CXXFLAGS="-arch x86_64" --prefix=/Path/To/My/ConvenientFolder/xercesInstall" from "extracted folder" of "xerces"
5) Tried the SAX2Count example from "bin" of /Path/To/My/ConvenientFolder/xercesInstall
I'll try to write some more tiny articles on creating/processing XML documents using xerces-c.
