>Description:
When trying to build from current pkgsrc tree, dovecot (and possibly others) 
fails to finish the configure phase with the following error:

checking for SSL... configure: error: The pkg-config script could not be found 
or is too old.  Make sure it
is in your PATH or set the PKG_CONFIG environment variable to the full
path to pkg-config.

Alternatively, you may set the environment variables SSL_CFLAGS
and SSL_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

To get pkg-config, see <http://www.freedesktop.org/software/pkgconfig>.
See `config.log' for more details.
*** Error code 1

Stop.
bmake: stopped in /usr/pkgsrc/mail/dovecot

>How-To-Repeat:
bmake clean clean-depends && bmake

>Fix:
If I add:

USE_TOOLS+=pkg-config

to the pkg's Makefile, it builds and installs perfectly.

I'm not sure if this is the right fix, but it seems to me that if a pkg uses 
pkg-config, the Makefile should be told about it.  I'm happy to be corrected if 
I'm wrong.
