>Description:
Despite the configure process finding db.h after building and installing 
databases/db4, the build stops with the following errors:

===>
===> There was an error during the ``build'' phase.
===> Please investigate the following for more information:
===>      * log of the build

*** Error code 1

Stop.
>How-To-Repeat:
Continue to try building PAM.
>Fix:
A workaround: create symlink /usr/include/db.h that points to 
/usr/pkg/include/db/db.h
