# the user/port can now set this options in the makefiles.
#
# WITH_NCURSES_BASE=yes - Use the version in the base system.
# WITH_NCURSES_PORT=yes - Use the port, even if base is up to date
#
# USE_NCURSES_RPATH=yes - Pass RFLAGS options in CFLAGS,
#             needed for ports who don't use LDFLAGS
#
# Overrideable defaults:
#
# NCURSES_SHLIBVER= 5
# NCURSES_PORT=     devel/ncurses
#
# The makefile sets this variables:
# NCURSESBASE       - "/usr" or ${LOCALBASE}
# NCURSESLIB        - path to the libs
# NCURSESINC        - path to the matching includes
# NCURSESRPATH      - rpath for dynamic linker
#
# MAKE_ENV      - extended with the variables above
# CONFIGURE_ENV     - extended with LDFLAGS
# BUILD_DEPENDS     - are added if needed
# RUN_DEPENDS       - are added if needed

#   if no preference was set, check for an installed base version
#   but give an installed port preference over it.
