Good catch. We have pushed the CK_DELETE_* macro update to chugins repo 
main branch.

There are few tools for diagnosing chugins at runtime:

1) run `chuck --chugin-probe` to see what chugins would be loaded (and 
from where)
2) run `chuck clarinet.ck` with the -v3 (verbose level 3) to see what 
chugins are actually loaded (with more error reporting here)

What do you see? Any errors?

We have updated the error reporting where warnings will now only be 
printed on verbose level 4 ("WARN") or higher. Also fixed a bug that 
resulted in false positive error reporting on linux ALSA. These will be 
part of the next release, 1.5.1.3.
