Bugzilla Bug 177516

The build procedure for EVMS will compile all plugins by default, provided the
system has support for the plugin, with one exception... the "ha" and "hb2"
plugins are mutually exclusive: they cannot both be built (the default being
only the "ha" plugin). The current ebuild for EVMS provides no way to select
the "hb2" plugin instead of "ha".

Could this choice be provided as a USE flag? Ie, which sets the "--disable-ha"
configure option if hb2 is desired?

Reproducible: Always

Steps to Reproduce:
1.emerge heartbeat
2.emerge evms

Actual Results:  
no hb2 plugin present in /lib/evms/*/


This is the relevant part of the configure output when emergeing EVMS:

evms-2.5.5-r6-hb2.patch

Patch against evms-2.5.5-r6 adding a hb2 keyword.

Why on earth they decided to name one module ha and one hb2 I don't know, but
anyhoo.

Fixed in CVS.
I added the USE flags hb and hb2 to be able to disable the support for
heartbeat-1/-2 even if it's installed.
Added the correct dependencies for both of them...
