Unfortunately we aren't going to be guaranteeing binary-level 
compatibility of the LCB module format for quite some time - it will 
likely change in every major version for quite a while yet.

Can you elaborate by 'recompiling only worked here in 1 of 20 cases'?

There's probably something we can do here. Currently widget source code 
is included in the extension when built using the extension builder 
(this will always be true of the community edition, and when we have our 
'extensions store/sharing portal', it will be one way we can ensure 
people aren't doing anything nefarious (any widget which is to be 
accessible from community will require the source is in the extension, 
and also that the compiled module in the extension matches the included 

So, we could actually tweak things so that we generate the module file 
at extension installation time.
