I'm working on some extra cool and useful additions to PEP 370. It's
going to make compilation and usage of custom libraries very easy. Sit
back and watch the slide show. :)
The site module has two new options. The --user-base option prints the
path to the user base directory to stdout.
$ ~/dev/python/trunk/python -m site --user-base
/home/heimes/.local
I install libxslt-1.1.19 into my ~/.local directory.
libxslt-1.1.19$ ./configure --prefix `~/dev/python/trunk/python -m site
--user-base`
libxslt-1.1.19$ make
libxslt-1.1.19$ make install
...
test -z "/home/heimes/.local/lib" || mkdir -p -- "/home/heimes/.local/lib"
/bin/bash ../libtool --mode=install /usr/bin/install -c 'libxslt.la'
'/home/heimes/.local/lib/libxslt.la'
/usr/bin/install -c .libs/libxslt.so.1.1.19
/home/heimes/.local/lib/libxslt.so.1.1.19
Now I compile lxml against the libraries and include directories in
~/.local. But first I have to add ~/.local/bin to PATH so lxml picks up
the right xslt-config binary.
$ export PATH=~/.local/bin:$PATH
lxml-1.3.6$ ~/dev/python/trunk/python setup.py build_ext --user

As you can see etree.so is going to load my local libxslt library
instead of the system one.
$ ldd /home/heimes/.local/lib/python2.6/site-packages/lxml/etree.so
linux-gate.so.1 => (0xb7fc5000)
libxslt.so.1 => /home/heimes/.local/lib/libxslt.so.1 (0xb7e89000)
libexslt.so.0 => /home/heimes/.local/lib/libexslt.so.0 (0xb7e78000)

Comments? :)
