The same story with ruby packages - most of them use ruby script which takes 
values of CC, CXX, C(XX)FLAGS from Config module 
(file /usr/lib/ruby/1.8/*-linux/rbconfig.rb). IMO there is no way other than 
patching these setup scripts one by one to accept CC, CXX, C(XX)FLAGS env. 
var. or taking flags via commandline switchs - IMO such patching doesn't pay, 
there is only one practical inconvenience which is raleted to passing CC/CXX 
values when ccache is used without symlinking compilers commands to ccache.
