Thanks for the quick response.
I had looked at that (./configure --help), but still wasn't sure what to change.  For "make install" to do the equivalent of "sudo apt-get install samba" it seems like there are a lot of destination directories (bin, lib, etc).  Is there a known set of .configure options that will essentially do what "apt-get install samba" does?
Regarding the module...
This is for a small embedded system (beaglebone) so that multiple PCs can access various networked files and trigger some switches (gpio pins).
Probably not very generically useful; but if I get it working I'll gladly submit it.
