You're on the right track, but didn't follow the FAQ entry exactly.  You can't 
build in the source directory or anywhere under the source directory.  The 
easiest way to set up to build is to have directories laid out like this:
     XXX/build
     XXX/install
     XXX/src
where XXX is whatever you like.  In the FAQ its "/oss" but anything works.

Have XXX/src contain the source tree, as a git clone or symlink elsewhere.  Then 
cd to XXX/build and do configure there, but reference XXX/src/configure.

The FAQ 6.21 really does explain the steps needed, but you must have the 
directories set up correctly, be in the correct directory, and have all the 
required packages needed for the platform you're building on.
HTH,
