More and more of my clients nowadays restrict where you can go to "get=20
things from the net". I have managed to convince management to allow=20
blanket permission to install CPAN modules for our code development. I=20
wish to install them en mass=C3=A8 using a "bundle" with the cpan(1) script=
.=20
However it doesn't seem to work right. I'm not sure if this is a Cygwin=20
issue or a CPAN issue. If the later then pointers would be appreciated.

In it's simplest form I cannot install even a single CPAN module due to=20
this error. Note that cpan(1) tries various methods to retrieve the=20
external CPAN module, including LWP, Net::Ftp, etc. I have ncftp and=20
have managed to configure it to properly use the proxy in order to=20
obtain stuff from the net. For example, I can ncftp to my server at home=20
from my client's machines by utilizing the proxy settings.

While cpan(1) fails to get the material with LWP, Net::Ftp, etc. It does=20
seem to succeed when using ncftp but then fails with an odd error about=20
trying to rename the file it downloaded and failing to:

$ cpan Algorithm::Diff
CPAN: File::HomeDir loaded ok (v0.80)
CPAN: Storable loaded ok (v2.18)
...
Trying with "/bin/ncftpget" to get
    ftp://mirrors1.kernel.org/pub/CPAN/modules/03modlist.data.gz
03modlist.data.gz:                                     161.78 kB  796.93=20
kB/s=20
Error while trying to rename=20
'/home/p6258c/.cpan/sources/modules/03modlist.data.gz.tmp3996' to=20
'/home/p6258c/.cpan/sources/modules/03modlist.data.gz': No such file or=20
directory
$

Yet I see:

$ ls /home/p6258c/.cpan/sources/modules/03modlist.data.tmp3996*
/home/p6258c/.cpan/sources/modules/03modlist.data.tmp3996
/home/p6258c/.cpan/sources/modules/03modlist.data.tmp3996.gz

IOW I see the "tmp3996" and then the ".gz" yet the cpan command tried to=20
rename a file with ".gz" and then ".tmp3996".

Help!?!
