easily installing modern Mercurial on RHEL6

[Hollis Blanchard]

I'm still waiting to see these RPMs, but I'm concerned about two things:

 1. They need to be relocatable, so that non-root users can install with
    'rpm --prefix /foo'. This doesn't happen automatically:
    $ rpm --prefix /scratch1/hblancha/tmp -ivh
    https://www.mercurial-scm.org/release/centos6/RPMS/x86_64/mercurial-4.0-0.9_rc.x86_64.rpm
    Retrieving
    https://www.mercurial-scm.org/release/centos6/RPMS/x86_64/mercurial-4.0-0.9_rc.x86_64.rpm
    error: package mercurial is not relocatable
 2. This is only mercurial core, not including hg-git, hg-experimental,
    or liblz4.

Unless I can find an rpm one-liner for all these packages, I don't think 
RPMs are going to solve this problem.
