devel/llvm10 is pinned by graphics/mesa-* despite upstream support for
newer and older LLVM versions. Try adding DEFAULT_VERSIONS += llvm=10
to make.conf(5) in order to avoid devel/llvm90.

Alternatively, https://reviews.freebsd.org/D25020 will reduce mesa-*
dependency among USES=gl consumers e.g.,

$ make all-depends-list -C editors/vim
-graphics/mesa-libs
-textproc/py-mako
-www/py-beaker
-devel/llvm10
-x11/libxshmfence
-archivers/zstd
-sysutils/coreutils
-graphics/libdrm
-devel/libpciaccess
-misc/pciids
+graphics/libglvnd
