Title: Ethereal plugins not loading on Linux ppc

Hi,

I am trying to add a plugin to ethereal (version 0.10.2). I have been successfully able to make the plugin work for Linux on the i686 architecture. However, when I cross-compile the code for the ppc architecture and run on a ppc platform, none of the plugins seem to load.  Can any one shed some light as to why this might be hapenning.

Below is the initial output of the strace for the ppc platform. In the trace, before it tries to open ethereal.conf file, I would have expected it to load the plugins directory (as is the case with strace output on the i686 platform).

Thanks.

Sandeep
