indeed adding MRCAT to SPADLIST and CATLIST makes MRCAT.spad and  MRCAT.o 
appear in the build directory.
Adding it to CATDOMS triggers an early error when compiling VECTOR.
However when it comes to compiling MRING, MRCAT is invisible as before:

   initializing NRLIB MRING for MonoidRing
   compiling into NRLIB MRING
   cannot produce category object:
(|MonoidRingCategory| R M)
   finalizing NRLIB MRING
   Internal Error
   Unexpected error in call to system function getSlotFromFunctor
