Well, we need the squeak-vm (with the "Mpeg3Plugin.c" fix) for ceibal
right-away.
It will be best, if you could provide with any of the following options  ::

a)
"squeak-vm-4.4.47 RPM for x86 "AND "squeak-vm-4.4.47 RPM for ARM".


                                           OR

b)
"squeak-vm-4.4.47 SRPM".

Thanks a ton !!!!

So, all we need to do is replace the "old" etoys.image and etoys.changes
with the "latest" etoys.image and etoys.changes, respectively?
If yes, then we would be needing the SRPM for etoys-5.0.2406. (Or the older
SRPM for etoys-4.1 would do ?)


Thanks and Regards,
Ajay
