Comment (by mascguy):

 Replying to [comment:23 bgilbert]:
 > How long are you planning to defer updating the non-devel `libpixman`
 port?  It's currently vulnerable to CVE-2022-44638, and also has a
 regression that makes OpenSlide unusable. If you'd like to let the new
 release bake in `-devel` for a while, I could prepare backports for both
 issues.

 The ARM build failure was the only blocker, so I'll go ahead and update
 the non-devel port ASAP. (Either later today, or worse-case, tomorrow.)

 And thanks for the heads-up regarding the vulnerability, as well as the
 offer to backport the fixes!
