Yeah, you're definitely right about configure being very customizable...but I don't know how to work around this.
You said configure is usually told where to install things. What tells it where to install things? Better yet, can you tell me where I can read more about building an installable source for Linux so that I understand what exactly goes on during the 'configure', 'make' and 'make install' process?
Try ./configure --help for basic info on how to use it. More generally, these things are autogenerated by the GNU tools autoconf, automake, and libtool. Be prepared for lots and lots of fun if you insist on hacking these things.

       gram socket to log information across systems.
