Hi all,

I'm running into an odd problem attempting to install the  
ZopeInterface package on Cygwin.

The relevant part of the build output is below.  The failure "cannot  
find -lpython2.4" appears to be merely because the link path (-L  
option) isn't being set correctly; the link line is missing the "-L/ 
usr/lib/python2.4" option.

I'm posting here in case any Cygwin-using Python experts can pass  
along pointers on triaging (or solving ;-) this problem.

Thanks!
John Whitley

P.S. Thanks to folks who responded to my recent rebaseall question.   
Alas, Google didn't bring up any of the recent
          discussion threads on that topic; my bad.
