Gentoo's ebuild has a bindist use flag:
enable_option() {
sed -i -e "/#define $1/a #define $1" \
include/freetype/config/ftoption.h \
|| die "unable to enable option $1"
}
disable_option() {
sed -i -e "/#define $1/ { s:^:/*:; s:$:*/: }" \
include/freetype/config/ftoption.h \
|| die "unable to disable option $1"
}
if ! use bindist; then
# Bytecodes and subpixel hinting supports are patented
# in United States; for safety, disable them while building
# binaries, so that no risky code is distributed.
# See http://freetype.org/patents.html
enable_option FT_CONFIG_OPTION_SUBPIXEL_RENDERING
enable_option TT_CONFIG_OPTION_BYTECODE_INTERPRETER
disable_option TT_CONFIG_OPTION_UNPATENTED_HINTING
fi
Crap. I looked right over the "!" in "if ! use bindist". So you are correct,
the problem occurs when support for patented hinting is enabled and
autohinting is disabled. Did I get it right this time? (I'm running on very
little sleep. Sorry for the confusion.)
