Unfortunately, yes.

Ruby packages follow "the ruby way". Which means that the chain is

   shell => Rakefile => extconf.rb (ruby script) => Makefile

In principle, everything should be fine. However, the CXXFLAGS and 
CFLAGS environment variables are *not* passed on by the generated 
Makefile. It only "listens" to cflags (lowercase)

I'm thinking that I will change the Rakefile of involved packages to 
pass CFLAGS / CXXFLAGS to the underlying Makefile.
