Ok, I just browsed through "What's new Python 2.2" documented, and ta-daa,
"it's now possible to set the flags used by dlopen() using the
sys.getdlopenflags() and sys.setdlopenflags()"! :)

I made a quick test program and it seems to work:

--cut--
import sys
import DLFCN

sys.setdlopenflags(DLFCN.RTLD_LAZY|DLFCN.RTLD_GLOBAL)

from pyeca import *

e = ECA_CONTROL_INTERFACE()
e.command("aio-register")
print e.last_string()
--cut--

This should print a list of audio objects including ALSA and JACK types.
Note that it's important that the setdlopenflags() is called _before_
importing pyeca.
