plug-in's in Ubuntu 8.10

[arce]

Hi,

I am trying to use a software (CERN's SEAL) based on plug-in's on an Ubuntu 8.10, but this distribution dose not have HAVE_DLOPEN defined and the plug-in's cannot be load.
Does someone knows if there is a way to define HAVE_DLOPEN or some turnaround to use plug-in's?

Many thanks,

Pedro
