Agree.  Something(s) needs to be done.  Fail early is a good strategy!

One could have some 'make checkconfig' target which could try to check 
especially externally set variables that can affect the compile flow in a 
tool.  And have it run early always, especially if it is quiet by 
default.  And some VERBOSE=1 flag that would print useful info (as well as 
make that 'make checkconfig' tell more what it is doing.  Since there 
already is the QUIET= option that starts to print everything which is 
done, verbose might not be the rigth name.  Not thinking of printing 
everything here, which is just unreadable, but some actually useful debug 
info.  PRETTY_VERBOSE=1 ? :-)

(drasi and trloii has 'make showconfig' which tells what internal 
configurations it has come up with internally, but that is not what we are 
after here.)

Try to run the DAQ. ;)

The upexps presumably if 'just' unpacking, i.e. not involved in the DAQ as 
such, only in the data unpacking.

That should only depend on ucesb, not on the other DAQ tools, and the DAQ 
should not depend on it.  Except if your normal file writing goes via 
ucesb, which I hope not...

upexps is a repository which ... needs help (it is not being properly 
maintained).  Could you tell which commit you are using in that?

Thank you for all the feedback!
