This is on Linux. It is a custom install. We don’t use RPMs but the tar ball of the binaries. This is why we have the config file when we create the software.
Please don’t top-post. Inline or bottom posting with trimming is customary here.
I’m not a source installer (or tar ball binary) expert but you seem confused by what ./configure ‘s role is in all of this. You claim to have installed world yet the error message you are seeing clearly indicates the server in question doesn’t see the compiled extension. And its concept of where to look for it is vastly different than your own. At this point you might as well just try copying files around and hoping that it works. But personally I’d suggest just strictly building from source with your desired customizations in a controlled (scripted) manner.
