I was referring to the problem that Andy Moreton reported.  If 
pkg-config isn't installed, autogen.sh should fail with this diagnostic:

Your system seems to be missing the following tool(s):
pkg-config (missing)

Here the problem and fix is obvious, as Óscar Fuentes already mentioned 
when he mentioned this diagnostic: he simply installed pkg-config.  In 
contrast, Andy Moreton reported this diagnostic:

Checking for pkg-config (need at least version 0.9.0)...
ok
Checking for pkg.m4...
Can't locate Automake/Getopt.pm in @INC

This is less obvious, but the problem can't be due simply to pkg-config 
being absent, as pkg-config ran successfully.  It must be something else.

The Automake diagnostic could occur on any O.S. platform, but so far it 
appears that the only people who've reported it are Microsoft Windows 
developers.  Perhaps the installation problem, whatever it is, is more 
likely on that platform.
