./configure: line 7347: syntax error near unexpected token `CPPUNIT,'

To build nut from source on Ubuntu, I installed autoconf, libtool (they were mentioned here), g++ and make, then ran ./autogen.sh and ./configure. I get an error:

./configure: line 7347: syntax error near unexpected token `CPPUNIT,'

Turns out, I had to install pkg-config as well.
