Description René 'Necoro' Neumann 2011-03-27 02:17:28 UTC 
When enabling the 'compression' module in prosody, it needs lua-bindings to zlib, else it fails:

Mar 27 03:23:34 modulemanager   error   Error initializing module 'compression' on 'jabber.necoro.eu': /usr/bin/prosody:118: module 'zlib' not found:

This is also described in its documentation: http://prosody.im/doc/depends

A lua-zlib ebuild is given in bug #360679 .

prosody-0.7.0.ebuild.diff

Here is a patch against prosody-0.7.0.ebuild. I took the liberty to mark 'zlib' as enabled by default, as I personally think, there is no harm in installing lua-zlib, even if it is not used (size of lua-zlib: ~61 KiB). And keep in mind, that the compression needs to be enabled explicitly anyway in prosody's config.

Also something like the following should be added to metadata.xml:

<flag name="zlib">Support for compressing XMPP streams when mod_compression is enabled.</flag>

(Yes - 'compress' or 'compression' would be some more self-describing, but having a short glance with 'euse -i zlib', some more packages are using it this way.)
Comment 2 Dirkjan Ochtman (RETIRED) gentoo-dev 2011-05-02 16:55:22 UTC 
This has been fixed in prosody-0.8.0-r1.
