I guess.. [I'll have to try this another day ]
you can do "-nodefaultlibs" and then specify all the libs by hand.   
That works (I originally did this).
It seems then that the driver has to replicate the multilibs stuff...

I'm not sure that it would produce less darwin-specific code than  
renaming the lib.

I'm also happy to file a radar for missing Bstatic/Bdynamic.

fortran is not part of any standard installation on OSX (yet..., of  
course, that could change).
On darwin 8 the gcc version is 4.0.1
I don't know whether the 4.2.1 version [from darwin 9] will be  
officially released
...  I've back-ported it (but, that's not an end-user thing)

if you want to deliver any different you have to choose
(a) the end user must install with admin rights  [to put stuff in / 
usr etc.]
(b) static linking of the missing bits

(b) is a lot simpler for me...
