play files with the extension *.pdf on vu+duo

[oversize]

I have a vu + duo with BH 2.1.4.
I would like to play some files with .pdf extension (normal pdf files) that are on usb pendrive.
Perhaps with the plugin Gemini3.2 v0.81-r0 can not play these * .pdf files?

I can not install the plugin geminiplugin_0.81-r0_mips32el.ipk in vu+duo.
When I write the telnet command:
root@bm750:/# opkg install -force-overwrite /tmp/geminiplugin_0.81-r0_mips32el.ipk

I get the answer:
Installing geminiplugin (0.81-r0) to root...

I think the plugin is not compatible with vu + duo and BH.
Do any of you know a plugin that reads .pdf file that is compatible with vu + duo and BH ?
