Actually, the way you specified CFLAGS overrides CPUTYPE. AFAIK you should set CFLAGS/CPUTYPE like this: CPUTYPE?=.... CFLAGS+=... Though bothering with CPUTYPE or CFLAGS is actually a waste of time if you ask me. I've never observed any measurable improvement in the speed of the system by setting these. Note that most ports which DO benefit from specialized CFLAGS (mplayer comes to mind) have an option called WITH_OPTIMIZED_CFLAGS. > > on another thread was said that make delete-old is > > also broken (and i suspect also delete-old-libs), so options in src.conf > > are pretty useless. all the problems seems to be triggered by > > Makefile.incl These options are not useless.

Obsolete files is there for files that will never be built again and are generally useless/broken (or break other stuff) when left on the filesystem.
