[CWB] rcqp installation / compilation

[Ruprecht von Waldenfels]

Hi,
I am (once again) trying to install rcqp on a linux machine, and an old 
problem surfaces (below) that I seem to have been able to solve last 
time, but I cannot figure out, how. This is on a 14.04 64 bit server.
It's the same error I got 18 months ago. However, the solution was to 
delete certain files from the distribution that I cannot find now.
What could be the problem? I am repeating the error here:

Best and thanks!

The INSTALL file says that flex / bison are needed anyway for installation, and your Makevars.in has all the necessary rules to rebuild the grammar (which don't fire because the pre-generated parser files in the distribution are newer than the parser source files).
