The problem is that mod_ssl requires an Extended API (EAPI) to get its
hooks into the openssl library. So when you  configure apache for
mod_ssl, you patch the API. The risk is that if you then dynamically
load a Dynamic Shared Object (DSO) module, if the DSO module was
compiled a while ago (before you extended the API), it will expect the
standard API so *might* fail with the new EAPI. Also, it might not! - it
depends whether the function calls the module makes have changed in the

You can either plough through the source and check or you can recompile
the module with the option -DEAPI (N.B. It is the *module* that you must
recompile with -DEAPI, not apache...)
