grpc modules has problem

ied is blazingly fast! but it has problems on installing grpc module. What I guess is grpc actually requires compilation of C code, I could not see any steps doing the compilation. npm install does have such step. Not sure if my guess is right, may need your comments. Here is the output after I installed grpc modules:

Have you tried ied install -b to actually build modules?
