[rsyslog] Which librelp does work with rsyslog-3.18.6 ?

[Beat Meier]

Hello

I'm using rsyslog 3.18.6 on debian 4.0 (backport of rsyslog)
There is no backport of a newer version with librelp support :-(
so I downloaded librelp-0.1.3 and compiled it on debian 4.0.
This will install librelp.so
I have moved this to /usr/lib/rsyslog
but rsyslog is complaining that he cannot find imrelp.so.
I have configured the module imrelp as noted some ware else.
I have now seen that debian version of relp (for debian 5.0) has
imrelp.so and omrelp.so defined.

Has the name of the shared object changed from an old release to 0.1.3?
Nor renaming librelp.so nor changing module name did work.
(renaming library results in an undedfined symbol: modInit)

Which release of lbrelp can I use with rsyslog V3.18.6 or can I use 
librelp only with rsyslog-4.4?

Greetings and thanks

Beat
