yeah .it wont .b'coz, as also written in the link u specified ,the
following things are to be done:

1)Writing the package's spec file to support a build root.
2)Directing RPM to build software in a user-specified build area.

what u did was the first point.
in order to direct the rpm to perform build in ur specified area u have to
change topdir entry in ur rpmrc file. the directory path u specify here
should support rpmbuild area structure i.e. SOURCES,RPMS etc all the 5
directories should be present over there(u have to create them manually).

place ur source tar.gz file in SOURCES and spec file in SPECS.
note that the path u specify as buildroot must be present in advance.
then follow the normal procedure. u need not even be logged as a root user
then!!

ur spec file should look like this:

 BuildRoot: /vobs/nightingale/server/product/code/process/ml_temp

 %prep
 %setup -q

 %build
 make

 %install
 make ROOT="$RPM_BUILD_ROOT" install


this will definitely work. mail me back what happpened!! i m curious to
know the results of my solution.
