So I compile cubemaps with HDR lighting using these steps.

map <mapname>
mat_specular 0
buildcubemaps
disconnect
mat_hdr_level 0
map <mapname>
buildcubemaps
disconnect
mat_specular 1
mat_hdr_level 2
map <mapname> (different)
map <mapname>

Yet when I distribute the map, people still see reflective purple checkerboards over the textures. I don't see them, but others do. Why is that?
