build.log (1.14.0)

No change with mupdf-1.14.0.

If you disable "lcms" in 0.13 (the USE flag has been removed in 0.14), does the build still fail?

You are correct, 1.13.0 succeeds building without "lcms". But 1.14.0 fails to build anyhow. See already attatched build.log. ;)

USE="lcms" is masked on ppc64, but nethertheless tries to build:

Would you care to open a bug upstream? With 0.14, it becomes impossible to build without lcms, so if lcms doesn't build on ppc64, it looks like we'll have to unkeyword it.

Upstream bugreport: https://bugs.ghostscript.com/show_bug.cgi?id=699960

Tried building from git-master, but with the same result.

[Comment 7 ernsteiswuerfel 2018-10-12 20:00:37 UTC]

Upstream is pretty quick. The problem has been identified and will be fixed sometime next week.

[Comment 8 ernsteiswuerfel 2018-10-16 16:57:16 UTC]

Upstream fixed the bug with commit:
