Thanks for your answer.
With "sncExample.stt" there is no error message from "make". But 
changing the name of the program to "sncExample2.stt" and changing the 
"Makefile" to:
ifneq ($(SNCSEQ),)
   # This builds sncExample as a component of example
   example_DBD += sncExample.dbd
   example_SRCS += sncExample2.stt
   example_LIBS += seq pv

   # The following builds sncProgram as a standalone application
#    PROD_HOST += sncProgram2
#    sncProgram_SNCFLAGS += +m
#    sncProgram_SRCS += sncProgram2.stt
#    sncProgram_LIBS += seq pv
#    sncProgram_LIBS += $(EPICS_BASE_HOST_LIBS)
endif

I get the following error message:

Mayby  I should do something else if I want to install a  new sequencer 
program?
