Chamilo 1.9.4 + Xapian in Ubuntu 12.04
Since php5-xapian bindings are not available due to license inconsistencies, you have to build the php5-xapian package yourself.
you can follow the instrucions on the xapian.org wiki: http://trac.xapian.org/wiki/FAQ/PHP%20Bindings%20Package
build packages:
	sudo apt-get build-dep xapian-bindings
	sudo apt-get install php5-dev php5-cli devscripts
	apt-get source xapian-bindings
	cd xapian-bindings-1.2.*
	rm -f debian/control debian/*-stamp
	env PHP_VERSIONS=5 debian/rules maint
	sed -i 's!include_path=php5$!include_path=$(srcdir)/php5!' php/Makefile.in
	echo auto-commit >> debian/source/options
	debuild -e PHP_VERSIONS=5 -us -uc 
	cd ..

 If you're using PHP 5.4, then subclassing Xapian classes in PHP doesn't currently work properly and the testsuite will fail with
 a segmentation fault. The wrappers work otherwise, so if that's all you need, you can build the package without running the testsuite
 by changing the penultimate command above to:

env DEB_BUILD_OPTIONS=nocheck debuild -e PHP_VERSIONS=5 -us -uc 

Then you can install the built package:

sudo dpkg -i php5-xapian_*.deb
