[Interface-dev] Problem installing ZopeInterface on Cygwin

[John Whitley]

Hi all,

I'm running into an odd problem attempting to build the ZopeInterface  
package on Cygwin.  FWIW, I've gotten the same results below with  
versions 3.0.1 and 3.1.0b1.

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 tried diving in to determine whether this is an issue with Cygwin's  
distutils install or an issue specific to ZopeInterface, but no  
luck.  I'm still a bit too new to the arcana of distutils...

Any pointers (or solutions ;-) greatly appreciated!
