I agree, but there's another big problem: autoconf. It runs far more
tests than most projects need (especially when using glib which takes
care of a large range of compatibility issues for you), and each run
takes longer than the actual compilation with a modest 4 core CPU. When
building roxterm I think I have to run configure 4 times: before making
a tarball with make dist, at the start of debuild before it can make
clean, then once for each version of gtk. On top of all that you often
have to run bootstrap.sh first.
