"...cannot be interpreted at compile time" I can't find the source of the error!

Many thanks!. I'm using the same version of the compiler.
Without arguments, I get

mpdec/decimal.d(35,20): Error: `mpd_new` cannot be interpreted at 
compile time, because it has no available source code
Error: cannot interpret `<error>` at compile time
mpdec/decimal.d(35,20): Error: `mpd_new` cannot be interpreted at 
compile time, because it has no available source code


Nothing like

"compile time context created here"

(this is what I would need to trace the error!)
