resolving this

It worked!
Had to put /usr/local/bin
to my PATH.
That was missing.

Yes I followed the instruction step by step.
/Library/Frameworks/Python.framework/Versions/Current/bin/
is in my path

Ok, it looks like a problem in the binary package. I'm putting lcantey in the
nosy list since I think he manages them.

Did you follow the instructions from the website ?

"""
After you install (OS X 10.4 and earlier)

This package installs the hg executable in
/Library/Frameworks/Python.framework/Versions/Current/bin. This directory may
not be in your shell's search path. The MacPython installer will have created an
entry in .profile for it but if your shell doesn't use .profile you'll need
configure it yourself or create a symlink from a directory already in your path.

Installed the following Packages

- Python 2.5.2 for Macintosh OS X 
(http://www.python.org/ftp/python/2.5.2/python-2.5.2-macosx.dmg)

- Mercurial 1.0.2 for OS X 10.4 (2008-08-13: Version 1.0.2 - Release version; http://mercurial.berkwood.com/binaries/Mercurial-1.0.2-py2.5-macosx10.4.zip)

Unpack, doppleclickinstall, no modifications.

Success message of python checked with python -V (Version 2.5.2 approved)

Success message of hg shows -bash: hg: command not found

Search for hg with "which hg" shows

no hg in /Library/Frameworks/Python.framework/Versions/Current/bin 
/Applications/MAMP/bin/php5/bin /Applications/MAMP/bin /bin /sbin /usr/bin 
/usr/sbin

Second try to install hg shows only Update runing, after success message same 
error.

Can you explain how you install hg (using which installer, etc) ?

Same error spotted:

Tried to install mercurial on Intel IMac MacOs X 10.4.11 (German).
After Success message of Installer, I try to run hg version and get the same 
error message.

If you tell me what specific output you need, i can look for it.

thanks

Could you paste the output from the mercurial installatin ?

I installed python (if I try python -V it says "Python 2.5.2") I installed
mercurial (if I try echo $PATH it says
"/Library/Frameworks/Python.framework/Versions/Current/bin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/jikes-1.22/src:/usr/local/apache-ant-1.7.0/bin")
but if I try hg version (as the manual suggests to verify the installation) it
says "-bash: hg: command not found". I installed Mercurial 1.0.1 for OS X 10.4
and in /Library/Frameworks/Python.framework/Versions/Current/bin I don't find hg
executable. What is the problem? thanks
