Installing & recording of optional software

[Parv]

Recently i had submitted databases/p5-DBIx-Simple port which can
optionally use other software to provide extra functionality.  Let's
use databases/p5-SQL-Abstract as an example of this extra
functionality.  Currently, DBIx-Simple port records SQL-Abstract as
runtime dependency if WITH_SQL_ABSTRACT is defined.

In order to use DBIx-Simple, SQL-Abstract port does not need to
preexist during or after the install of DBIx-Simple.  It is just
that SQL-Abstract functionality will not be available until
SQL-Abstract is installed.

What i am trying to say is for DBIx-Simple port, IMO, recording of
SQL-Abstract as runtime dependency is wrong, and i need a better way
to inform the user that DBIx-Simple can use SQL-Abstract and install
the optional port if indicated so via WITH_SQL_ABSTRACT or some such
variable.

Alternatively, only a message can be printed -- w/o installing any
optional software -- telling the user that DBIx-Simple can use
other software & they themselves need install it separately.

Comments?
