This stack trace doen't really help me - there is no data as to what line, what parameters where send to the function, and in total - I don't know what resource is missing.
How can I get a better stack trace?
Try to look at the Mono Project.
They have a module for the Apache server called «mod_mono».
Hope this helps.
Try the Mod.Mono
This handles ASP.NET 4.0 (with the exception of Entity Framework).
See the compatibility for more information on what Mono is compatible with.
I have created Web application in Mac OS and able to build it.
On dnx web i get the following error:

I have tried the suggestion in the below question
dnx kestrel "System.EntryPointNotFoundException: uv_loop_size"
and set DYLD_FALLBACK_LIBRARY_PATH.
Yet unable to resolve the issue. Any ideas to resolve it.
