selfupdate does a sync for you, unless you run selfupdate with the --no-sync flag. It is possible for sync (whether performed separately or as part of selfupdate) or the subsequent portindexing to fail; the debug output produced by running with the -d flag should let you see if that's happening. > It's not the individual libraries that I'm worried about.

Sounds like this may be a case where not listing openmaintainer for blender and its dependencies that you maintain would be a valid choice. I know you added a lot of blender's dependencies specifically for blender to use, so holding them back in order to be compatible with blender may be workable here. In general though, that's hard to do, since most libraries are used by more than one port. Holding back a library to be compatible with one port may not be the right choice for other ports that depends on the library. > Is there some way that I can signal not to update certain libraries without > verifying against blender?

A comment in the portfile, near where the version is defined since that's where someone updating the port will look first, is a great way to communicate that.
