Robin,

if changing man.conf does not work, as Stan recommends, another
option is to pull the rpm and install locally.

if you use mozilla firefox to pull file, it's downloader can be
paused and restarted if you have need, and will resume a download
if download is broken.

i imagine there are other download programs with ability to resume
or continue a broken download.

having read your bug report, i wonder if your sysadmin is not an
"oos head" with his concern for getting malware. ((GBWG))
