LoadPlugin: failed to initialize shared library
/usr/compat/linux/usr/local/Adobe/Acrobat7.0/Browser/intellinux/nppdf.so
[/usr/compat/linux/usr/local/Adobe/Acrobat7.0/Browser/intellinux/nppdf.so:

I get this message after i instled the "linuxpluginwrapper" what else
do i have to do to avoid this.  i heared that i should make changes to
the /etc/libmap.conf, the question is how and wich line in particular.

life harder
