Does the libs element from cblas' dub.json not handle that 
library linkage? I suppose I should also mention that it was 
compiling fine before I actually used a function from the library 
in my code.

If it does work with OpenBLAS, that would seem to suggest that 
"Works with OpenBLAS and others" is a bit more restrictive than 
it sounds...
