I was able to change the default CFLAGS by putting the CCFLAGS and the
CFLAGS values in my environment before running "perl Makefile.PL".

I would guess that this could be considered a bug, because its not too
uncommon for default CFLAGS to be changed during a compilation.

That's not where spamc is getting them.  They're hard-coded in the configure 
script:

ringbill# grep 'O2' -B1 spamc/configure
  if test "$GCC" = yes; then
    CFLAGS="-g -O2"
--
  if test "$GCC" = yes; then
    CFLAGS="-O2"

You were right.  It has to go in the environment.

In other words, this doesn't work:

# perl Makefile.PL CCFLAGS="-O"
# make

But this does:

# perl Makefile.PL
# CFLAGS="-O" make
