No SF2 Player in LMMS_0.4.10 ?

Having trouble with LMMS? Ask about it here.
I have recently installed LMMS_0.4.10 on Linux (Precise Puppy 5.5) - that was the only version available, apparently.

I have also installed Midi Soundfonts (Fluidsynth_3.1-5) GM and GS (into /usr/share/sounds/sf2/) with the intention of playing midi files.

However, the required 'Sf2 Player' instrument plugin is missing from LMMS_0.4.10.
Should this plugin have been included with LMMS_0.4.10?

Is there somewhere I can get just the LMMS-based 'Sf2 Player' plugin that will function in my particular LMMS on Linux without having to download LMMS again into some other Linux OS? (I am on a dialup modem and want to avoid further sizeable downloads just to fix this).
Thanks
dave :D
the problem may be that you havnt the required library for building the sf-player, search using your package manager for libfluidsynth-dev and install, then just reinstall lmms
