Hi,
when you need to link a node library into your package during build
(debian/rules), no more use "ln -s /usr/lib/nodejs/npm-name" but
instead, use:
override_dh_auto_build:
    # ...
    ln -s `nodepath npm-name` node_modules/
nodepath is included in pkg-js-tools. See nodepath -h for more.
Cheers,
Xavier
