That's mostly distro-specific and this is where I have very limited
knowledge. But you can set the module path via the environment, use
RSYSLOG_MODDIR=/path/to/modules/ . There is also a -m option to do the
same, but it currently is read too late to help with the core modules.
On my 64Bit system adding --libdir=/lib64 often helped with such
problems when I encountered them. Not sure if that's the right cure...

You are *really* brave!
