Yup, that's what you have to do to solve this properly.  Although the new 
version could be fully compatible with the old one, there is no way for the 
build system to test that compatibility, so by default it enforces the safest 
option, which is to not allow the build to continue.  I added the module 
checking mechanism because in the past linking incompatible modules together 
has caused numerous some really strange and often extremely subtle bugs to 
turn up here at APS, in some cases only being noticed days or even weeks after 
we booted the IOC.

If you as the author of the IOC are certain that the changes did not involve 
modifying any struct or class definitions, or changing any routines in an 
incompatible way you can edit your application's configure/CONFIG_SITE file 
and set CHECK_RELEASE to WARN (it also accepts NO but I don't recommend using 
that) which will then allow the build to complete despite the warnings.
