 Allin,
 Okay, fine. I still get this, however:
 clive@clivubu:~/gretl-2015d$ ./configure --prefix=/usr/local
 --enable-quiet-build --enable-openmp 
Note: you didn't add --enable-build-doc. So we see...
 Configuration:
  Installation path:                      /usr/local 
[...]
  Build gretl documentation:              no 
[...]
And therefore...
 clive@clivubu:~/gretl-2015d$ make pdfdocs
 make -C
 make: option requires an argument -- 'C'
 Usage: make [options] [target] ... 
the resulting failure should not be a surprise.
