Ok well I'm 90% there.
In the gxine plugins folder there are a bunch of files I'd rather not go sorting around like crazy.
"gxineplugin.la jritypes.h Makefile.in npunix.lo plugin.c plugin.o
jri.h Makefile npapi.h npunix.o plugin.h
jri_md.h Makefile.am npunix.c npupp.h plugin.lo"
None of these is your average so plugin file so I'm a bit confused here.
And just from what I've tried on my own, it looks like it needs to be compiled so I tried a "make" command and nothing. Of course my complete knowledge here comes from what I know from other installiations so it's not that vast.
