--- Comment #18 from Jan Beich <jbeich@FreeBSD.org> ---
(In reply to Mark Linimon from comment #17)
Runtime. Loading more than one libLLVM.so version can lead to crashes. A
consumer cannot block other consumers from switching. If only one devel/llvm
existed (like in OpenBSD Ports) then it'd be mainly about making consumers
build.

For example, OpenGL application can load LLVM via graphics/mesa-dri and as =
part
of its own usage. In the past emulators/rpcs3 was affected until it switche=
d to
static linking and later to bundled LLVM copy of development snapshot.

Currently, I suspect lang/clover is affected. Pining mesa-dri and blocking
OpenGL-based LLVM consumers from switching just because a barely usable Ope=
nCL
implementation isn't compatible yet due to being based on very old upstream
release would be silly.
