I've installed Python 2.6.4 into (a subdirectory in) my home directory on a Linux machine with Python 2.3.4 pre-installed, because I need to run some code that I've decided would require too much work to make it run on 2.3.4. (I'm not on the sudoers list for that machine.)
I was hoping I could run ~/Python-2.6.4/python setup.py install
(from the PyYAML directory in my home directory, where I untarred the
PyYAML sources) and it would be smart enough to install it into my
local Python 2.6.4 install. But it's not. (See the P.S.)
Is it possible to install PyYAML into my local Python install, so that "import yaml" will work when I invoke that Python? If so, how do I do that?
P.S. Here's the output when I ran ~/Python-2.6.4/python setup.py install:

Look into the
--homeor--useror--prefixswitches for setup.py. These control where files get installed to.From your build log though I'm not sure that's the problem. It looks like it's failing to find yaml.h. Is that part of the PyYAML sources? Or is it part of libyaml which PyYAML requires but you've neglected to install?
I didn't install Python correctly. When I followed Crast's instructions in https://stackoverflow.com/questions/2278028/how-do-i-work-around-this-problem-creating-a-virtualenv-environment-with-a-custom/2278059#2278059, I was then able to install PyYAML without problems. (With no need for virtualenv.)
