Okay, I did a little headerfile digging:

You should create variables like `serveez-verbosity' with a call to 

  SCM scm_c_define (const char *name, SCM value);

(or maybe scm_sym2var in 1.4?)

It does the same as gh_define, but returns a `variable object', that
is an object which stands for a variable.  You can use the
SCM_VARIABLE_REF macro to extract the value from a variable, after
reading in the config file.

I don't get which libraries you talk about here?  Protocol libraries
or so?  Anyway, in Guile, you would modify them like this

  (set! serveez-load-path (cons "c:/winnt" serveez-load-path)

or
  
  (set! serveez-load-path (append serveez-load-path '("c:/winnt")))

In Guile:

  (putenv "SERVEEZ_LOAD_PATH" "/usr/local/lib")
