My guess is that it is a file system ownership/ permission issue.  Vista is=
 more picky than XP.  Take a look at all the folders down to /home/p6258c/.=
cpan/sources/modules/ with Windows Explorer -> Properties -> Security and B=
ash 'ls -l'.  If something looks strange, you might be able to fix it with =
Windows Explorer, 'chmod', and/or 'chown'.


I try to make sure that I only install and administer Cygwin and Cygwin sof=
tware while logged in as Administrator.  For Perl modules, I find that Cygw=
in packages (if available) work better than CPAN.


When one of my Cygwin installs starts acting up, I move C:\cygwin aside and=
 start over -- either with a fresh download, or with an archived copy of C:=
\cygwin\setup.


HTH,

David
