I need to install mercurial to make hg command work on my CentOS-5.2 Linux.
In Fedora yum is recognizing the mercurial package and installing the dependencies on its own but in case of CentOS yum is unable recognize mercurial. So I had to manually download mercurial RPM and then install it.
But while installing I am hitting the following dependency and I believe that I need to install a latest version RPM package manager to get rid this error, isn't it.

=======================================================================
rpmlib(PayloadIsLzma) <= 4.4.2-1 is needed by mercurial-1.0.2-12.x86_64
=======================================================================

Can somebody send me the pointer to the package which contains rpmlib(PayloadIsLzma)

Not exactly the answer to your question, but anyway...

On your Fedora box where you successfully installed mercurial you can pack it into one self-contained executable using statifier (http://statifier.sf.net) or Ermine (http://magicErmine.com)
Then you can just copy resulting executable no nearly any Linux box and it should work

Did you try 'mercurial-hgk-0.9.5-1.el5.rf.i386.rpm'
from
http://dag.wieers.com/rpm/packages/mercurial/ ??

If you want an answer to your rpm question,
please tell which package. (complete name
like the above example and a link to where
you got it.)
