Hi Stefan,
   I made some progress. Understood what was wrong in the make phase. You have only to add the option -arch i386 in the CFLAGS line of the makefile.
Then the make is ok, it produces the 3 executables. drs_exam and drscl seem to work correctly. 
DRSOsc.app does not work as app, in the sense that if you click it, an error message comes saying "You can't use this version of the application DRSOsc.app with 
this version of Mac OS X. You have Mac OSX 10.6.8. The application requires Mac OS X 10.7 or later. "
If you execute drsosc from the terminal, the graphical window pops up, the waveform is displayed, but you don't have access to the graphical interface, no button works, you can't do
anything. To quit the app, you have to kill it from the terminal with the kill command.
But anyway is a progress with respect to yestarday.
Any idea/suggestion to overcome the above problems ? I thought it is a problem with the graphical library (xwWidgets) but I have checked it, it's ok, I have also reinstalled it
(release 2.8.12_3) but nothing changed.

PS. the chip test output (done with the drscl ) is the following (see below). Is it normal or what ? THANKS.
