There is a generic broker to get a "namespace" The broker asks every alread=
y=20
registered Y2ComponentCreator to create a component for a namespace. The=20
order is a bit tricky, but basically WFM should act first IIRC (there is so=
me=20
code in the Y2ComponentBroker about priorities and directory prefix levels).

=46or YCP modules, the Y2CCWFM reacts by looking up the corresponding ybc f=
ile=20
(YCP bytecode) file.

=46or perl, Y2LangLoader loads the Perl bindings component from the=20
libpy2lang_perl.so file. This component registers its creator and this=20
creator is able to look up the .pm file.

So, the question is, if you see libpy2lang_perl being open. It should put i=
nto=20
a log something about starting and stopping the Perl interpreter.

SuSE 9.2, right?

Hope this helps. If not, please, attach the strace.
