It may be so. The reason I thought it was more general, is I get a somewhat similar error when trying to build the websocket demo code found here: https://wiki.dlang.org/User:Csmith1991/Vibe.d_Documentation/websocket

This is what I get:

websocket_chat ~master: building configuration "application"...

Hmm, did this error occur when trying to build the websocket example from the Vibe.d source tree. What version of Vibe.d do you build?

I tried both 0.8.5 and 0.8.6-alpha.1.

I may have misunderstood your question re. the Vibe.d source tree. I also did try the tiny hello.d (Hello Vibe.d) at code.dlang.org/packages/vibe-d. It ran, and was listening and responding on 8080, in spite of the yellow text in the log saying "Failed to listen on 0.0.0.0:8080".

Did you clone the vibe.d repository and go into the examples/websocket directory to run the websocket example or where did you get it from?

I have now cloned the vibe.d repo. The vibe.d/examples/websocket did build and run w/o problems.

I also tried to dub build the vibe.d/examples/http_server, but that ended like this:

Hmm could it be that this is due to your installation as it looks like your
linking with a different standard library than your source include paths have.
How did you install D and could you check that DMD is using them correct
standard library?
You can see the imports and linker commands when compiling with -v (e.g. hello
world).

I installed using the installer, first dmd.2.085.0.dmg, then dmd.2.085.1.dmg. The same on three different Macs.

Here's the output from compiling "hello":
