Bugzilla Bug 200279

ucd-snmp/extensible extension, containing "exec" keyword support, was dropped
from default net-snmp build between 5.2 and 5.4. Can you add USE flag for
re-enabling it by adding ucd-snmp/extensible to --with-mib-modules configure
option ?

Reproducible: Always

Honza, but why do you need this? Reading ChangeLog it's clear that was done on
purpose:

   * agent/mibgroup/: ucd_snmp.h, agent/extend.c,
     ucd-snmp/extensible.c:

   Drop the old UCD extensible module from the default build.
   Rely on the reworked (cached, valid syntax) "extend" module instead.

thus I doubt we'll include something that supposed deprecated by upstream
without really good reasons. What's wrong with "extend" module?

To use extend, you need to rewrite not only configuration file, but also
application(s) which use that snmp informations. That "valid syntax" means that
it is not possible to put same values to same MIBOID as you have in "exec"
configuration.

You know, upstream have some reason to drop the old module only from the
default instead of droping it from source completely. For example, to provide
time for transition.

Honza, I've added extensible USE flag, which enables this functionality. Hope
this solution suits your needs. Enjoy.

Forgot to say, added in net-snmp-5.4.1-r3.ebuild.

Thanks. Works perfectly.
