Quick start instructions don't work because of missing file indexer

Quick start instructions at http://www.dataparksearch.org/dpsearch-quick-usage.en.html don't work because there's no file indexer in /usr/local/dpsearch or in PATH.

indexer is installed into /usr/local/dpsearch/sbin/ directory by default.
If you do not specify any SQL server when you run configure then indexer is not built.
Please check you have specified at least one of MySQL, PgSQL or SQLite when run configure.

I'm just trying to get a quick glance at dataparksearch and certainly didn't RTFM. Would it make sense to make configure fail if no SQL server is specified or give a

********************************************************************************

?

As I am aware of it gives it like that:

No database selected! indexering part will not be compiled
If it's incorrect, use --with-XXX where XXX is your preferred database type

My intention was just to make it more visible (see above) and maybe print it as one of the last statements of configure to improve intuitive usage.
