Description Austin English (RETIRED) gentoo-dev

I noticed that this package failed to build in a fresh chroot, while it was installed on existing systems. A bit of debugging led me to bug #491496, which looks similar, but this is a separate issue.

If x11-proto/xcb-proto-1.12-r2 is installed, the build fails:

downgrading xcb-proto to 1.11 works around the issue.

I don't disagree yet that this is something we should improve on if necessary with some dep locking, but curious - why are you mixing package visibility here?

Internally we have several profiles/features, and xcb (X11 in general) are masked. I noticed this on a profile with it unmasked.

I think the unmasking could be tweaked to avoid this, which I'm looking at, but wanted to report the issue in case it affects others.

For reference, installing 1.12 versions of both works:
x11-libs/libxcb-1.12
x11-proto/xcb-proto-1.12-r2

libxcb-1.11 and xcb-proto-1.11 are no longer in the tree.
