That doesn't really help.

If you ship a package that depends on both of those math.scm's and
resolves things the way you had, people would have to install one
math.scm in /usr/src and the other in whatever the other directory
was. I don't think this is acceptable, for instance, I use machines
regularly where I do not have write permissions to /usr/src but I
still like to install software on them. Hence, finding modules in a
directory related to Guile's $prefix makes much more sense, at which
point you can drop the (usr src ...) bit, at which point you are back
to the original problem of making sure the namespace stays
unique. Note that filenames in the module namespace don't have to stay
unique, just module names, which are hierarchical.
