According to both the Guile manual and the output of "guile compile -h":

  -L, --load-path=DIR   add DIR to the front of the module load path

In other words, it behaves as documented.  The idea is that you should
pass multiple --load-path options, one for each DIR.

Having said this, one could reasonably argue that the long option name
is misleading, and I tend to agree.  On the other hand, the current
behavior has the advantage of allowing _any_ directory to be added, even
if its name contains a colon, and thus allows the creation of more
robust code.

We might want to change the long option name (while continuing to accept
--load-path for backward compatibility), but I can't think of a good
name.  Any suggestions?

    Thanks,
      Mark
