Some comments on the patch:

# In install_hue.sh there are 2 variables related to logs: LOG_DIR and 
DESKTOP_LOG_DIR. While they may be required by the environment, it may be 
cleaner to keep it to one.
# In hue-app-postinstall.tpl, hue-app.prerm.tpl and other app related files 
kept some variables that are removed in other files, such as ROOT=/usr/lib/hue
# In a few places user name "hue" is used without defining USER=hue
# Build successful on Precise
# Package install successful

Tried a few commands. Met this problem:

Obviously, test_windmill also fails.

Off-topic question: why the build system does not detect change in the src 
files, only `rm -rf <component>/build`?

> Currently Hue packaging does unfortunate things with permissions and 
> mutability of things under /usr/lib/hue. We should make sure our virtual env 
> is relocatable and can be used in a R/O fashion and we should move mutable 
> bits (desktop.db and app.reg) under /var/lib/hue.
