Error trying to install libwww using Cygwin

I have experienced problems trying to get an error-free installation of 
libwww v5.7.6 when using Cygwin  v1.5.9 (both the most recent Release 
versions).  I first installed the prerequisite modules.  The creation of 
libwww's Makefile went smoothly.  In that process I indicated that I did 
want to create the GET, POST and HEAD aliases  Execution of the make 
itself however, ended in this error message:
$ make install
Cannot forceunlink /usr/bin/HEAD: No such file or directory at 
/usr/lib/perl5/5.8.2/File/Find.pm line 888
make: *** [pure_site_install] Error 255

Now, Cygwin is a bit weird, because usually a pathname starting with 
"/usr/lib" actually refers to the DOS directory "C:/cygwin/lib", 
assuming cygwin was installed at the top of the C: drive.  Consequently, 
I would expect there to be files in C:/cygwin/bin/, and, indeed, GET is 
there.  (So make got that far.)
Any idea what is going on?

Thanks, Matt Evett
