Yeah, the Makefile distributed with Mercurial has several different
targets:

% cd mercurial-1.0.1
% make
Commonly used make targets:
  all          - build program and documentation
  install      - install program and man pages to PREFIX (/usr/local)
  install-home - install with setup.py install --home=HOME (/u/eis)
  local        - build for inplace usage
  tests        - run all tests in the automatic test suite
  test-foo     - run only specified tests (e.g. test-merge1)
  dist         - run all tests and create a source tarball in dist/
  clean        - remove files created by other targets
                 (except installed files or dist source tarball)

Example for a system-wide installation under /usr/local:
  make all && su -c "make install" && hg version

Example for a local installation (usable in this directory):
  make local && ./hg version


I normally install Mercurial using a simple

  python setup.py install --home=$HOME/opt

and add $HOME/opt/bin to PATH and $HOME/opt/lib/python to PYTHONPATH.
That has worked great for me on several machines.

At the top of hgweb.cgi you will find these lines:

# adjust python path if not a system-wide install:
#import sys
#sys.path.insert(0, "/path/to/python/lib")

You can use those to fix PYTHONPATH if it is not set correctly already
when you execute the CGI script.
