i'm compiling directly from sources.
my platform is a bit weird, it's a cobalt Raq2 and not all softwares are
available from pkgsrc.

anyway, for the moment i use the following command line to tell the make
what to do :

make -f Makefile.init makefiles \
    'CCARGS=-DHAS_MYSQL -I/usr/local/include/mysql' \
    'AUXLIBS=-L/usr/local/lib/mysql/ -lmysqlclient -lz -lm'

i don't see how to change it to follow your advice (sorry i'm a newbie)
