# It is sometimes requested, by both users and certain devs, to have sys-devel/gcc[graphite]
# in BDEPEND. This has not been done *on purpose*, for the following reason:
#  - darktable can also be built with llvm-core/clang so we'd have to have that, as an alternative,
#    in BDEPEND too
#  - there are at least two darktable dependencies (media-libs/mesa and dev-lang/rust) which
#    by default pull in llvm-core/clang
#  - as a result of the above, for most gcc users adding the above to BDEPEND is a no-op
#    (and curiously enough, empirical observations suggest current versions of Portage are
#    more likely to pull in Clang to build darktable with than to request enabling USE=graphite
#    on GCC; that might be a bug though)
