Bug#707879: apache2: mod_mpm_itk.so: undefined symbol: cap_set_proc

[Ángel González <keisial@gmail.com>]

Package: apache2
Version: 2.4.4-2
Severity: |important|


Using apache2 2.4.4-2 (from experimental) with the itk mpm fails with:
> apache2: Syntax error on line 140 of /etc/apache2/apache2.conf: Syntax
> error on line 2 of /etc/apache2/mods-enabled/mpm_itk.load: Cannot load
> /usr/lib/apache2/modules/mod_mpm_itk.so into server:
> /usr/lib/apache2/modules/mod_mpm_itk.so: undefined symbol:
> cap_set_proc Action 'restart' failed.


libcap (package libcap2) doesn't seem to have been linked with it:

mod_mpm_itk.so wasn't linked using -lcap ?
