Hi

I have recently installed GIT so that I have a little more flexiblilty in adding third-party Symfony2 bundles. However, when I use the command "php bin/vendors install" all my vendors seem to install or update, but then I get an error massage afterwards which states the following:

[ErrorException]
Notice: Use of undefined constant LIBXML_COMPACT - assumed 'LIBXML_COMPACT' in /Users/barry/Symfony/vendor/symfony/src/Symfony/Component/DependencyInjection/Loader/XmlFileLoader.php line 212

I am unable to load any third-party bundles at the moment as this also gives the same error message

I have already experienced that this is a great community, with help being given where possible, and I help where I can too, but this one has me stumpted

Can anybody help?
