On Linux all the tests fail like this:
t/01-argless.t ......... Cannot locate native library './01-argless'
in method postcircumfix:<( )> at /home/moritz/p6/zavolaj/blib/lib/NativeCall.pm6:119
Changing the test to load ./01-argless.so would fix it, but I guess that kinda goes against the idea behind the changes to the loading behavior.
I'm seeing the same problem. But from a quick inspection it seems that all the test files have is native("./lib") so I'm not sure what's going on. I'm gonna bisect a bit and see what I find.
I think this issue has been fixed now. Please reopen if it's still a problem.
