The %{buildroot} directory is just a temporary location during an rpmbuild
for storing files which will end up in the final RPM.

It's the %files step which indicates which files are included in the RPM and
where they will be installed to.

When the gpt RPM is installed, the files are located in /usr/lib/gpt and
/etc/profile.d/.

No. You might want to see the RPM-Howto to see which sections of a RPM SPEC
file have an impact on the RPM building process and which have an impact on
the final RPM when it is actually installed, see:

  http://www.rpm.org/RPM-HOWTO/

I don't know much about Debian's alien, perhaps it was designed mostly for
binary RPMs rather than SRC-RPMs?

Cheers,
