List of common errors for the module libcanberra.
Error - /libcanberra.schema permission denied
System details: October 19th, 2010 - GNOME 3.0 GIT - Gentoo
Cannot write /libcanberra.schema
Cause: User has no write permission for / and the libcanberra.schema does not belong there! There is a problem with the path to GConf's schema dir. See here for details.
Solution: Add module_autogenargs['libcanberra'] = autogenargs + ' --with-gconf-schema-file-dir=<_YOUR_PREFIX_PATH_>/share/GConf/schema' to your .jhbuildrc
