 When using a source plugin with a stage2 compiler built with the devel2
 flavour, there are a fair few warnings about hptSomeThingsBelowUs.

 {{{
 WARNING in hptSomeThingsBelowUs
   missing module CoercePlugin
   Probable cause: out-of-date interface files
 }}}

 I don't know if this just started happening or has been going on for a
 while. Is this warning cause for concern? Everything appears to work as
 expected despite this hiccup.
