[Chicken-users] possible dependency issue with message-digest egg

[Brian St. Pierre]

I'm using message-digest 3.0.5 and csc 4.7.0 on ubuntu 12.04 x86_64

This minimal example works fine in the interpreter but fails when compiled:

    (use sha1 message-digest)
    (display (message-digest-file (sha1-primitive) "mysha1.scm"))
    (newline)

The error is:

% ./mysha1

Error: call of non-procedure: #<unbound value>

        Call history:

        ##sys#require   
        ##sys#require   
        ##sys#require   
        mysha1.scm:2: sha1#sha1-primitive       
        mysha1.scm:2: message-digest-item#message-digest-file <--

In the process of experimenting, I noticed that adding 'posix' as a 
dependency would fix the error. This program works as expected:

    (use sha1 message-digest posix)
    (display (message-digest-file (sha1-primitive) "mysha1.scm"))
    (newline)

I don't know enough about how dependencies are supposed to work to know 
if this is the right way to solve it, but this patch makes the first 
program above work as expected:
