# Versions of additional stuff:
IMAGE=1.2.6
MIXER=1.2.8
NET=1.2.7
TTF=2.0.9

# Record toolchain & other info for the build log:
slackbuildinfo

# Paths to skeleton port's source & real Slackware source tree:
export CWD=$SLACKSOURCE/$PKGSERIES/$PKGNAM
export PORTCWD=$PWD

# Temporary build locations:
export TMPBUILD=$TMP/build-$PKGNAM
export PKG=$TMP/package-$PKGNAM
mkpkgdirs # Delete & re-create temporary directories then cd into $TMPBUILD

# Determine the CFLAGS for the known architectures:
case $PORTARCH in

   powerpc) export SLKCFLAGS="-O2" ;;
